How Gulf Disruption Raises the Cost of Doing Chemistry
Long before a direct shortage of a specific research chemical, the reagents, solvents and purification tools needed to make it become more expensive or harder to obtain. For research chemists, CDMO production teams and pharma and biotech R&D labs, this upstream pressure changes the cost of every experiment, every analysis, every batch.
The majority of the discussions of the current crisis of supply chain disruption in the Persian Gulf have focussed on oil and commodity petrochemicals; we see headlines covering ethylene prices, polypropylene availability and the cost of basic plastics. However, for researchers, pharmaceutical chemists and CDMO production teams, the real concern is different and more immediate: the reagents, solvents, and process chemicals used daily in synthesis, purification and analysis – almost all of which connect, within a handful of synthetic steps, to Gulf feedstocks.
Key components of reactions, work ups and purifications; polar aprotic solvents that make solid-phase synthesis possible; low-polarity hydrocarbons that are the lifeblood of normal-phase chromatography; the acetonitrile that runs through nearly every HPLC and LC-MS in every lab and QC suite in every pharmaceutical company on earth. These are all downstream products of the same feedstock chains that connect back to the Gulf.
Now, with these chains facing disruption, the first thing that changes is not the price or availability of a target compound, but the price and availability of everything used to make it.
Wave One |
Days to Weeks
Gulf-produced chemicals cut off or restricted
Methanol, ammonia, formaldehyde, acetic acid, formic acid, chlorine, HCl, caustic soda, sulphuric acid. Alongside headline grabbing oil and gas, they are among the products that physically originate in the region and face immediate price increases.
Wave Two |
Weeks to Months
Downstream lab and process chemicals tighten
The solvents and reagents of daily chemistry (DMF, acetonitrile, NMP, hexane, IPA) reprice or go on allocation as their feedstocks become expensive or constrained. Lab budgets compress before any chemistry changes.
Wave Three |
Months Onwards
Reagents, building blocks and substrates follow
Fmoc amino acids, coupling reagents, specialty monomers, fluorinated building blocks and other advanced intermediates reprice as their own synthesis routes are affected by the same upstream pressures.
Wave One: Restriction of Direct Gulf Products
Gulf producers benefit from relatively cheap energy (derived from the abundant local gas), making them cost-competitive global suppliers of fundamental chemicals which are energetically intensive to produce. Particularly relevant is hydrogen production and its subsequent use in the Haber process to make ammonia, the hydrogenation of carbon monoxide to produce methanol and in hydrodesulphurisation (the removal of sulphur contaminants from gas and oil, which are ultimately processed into sulphur or sulphuric acid).
The region produces approximately 10–14% of global methanol (Saudi Arabia and Iran combined producing over 14 million tonnes per year), ~25% of global nitrogen exports (ammonia and urea from Qatar, Saudi Arabia, and Iran) and ~24% of global sulphur production – virtually all of which must exit through the Strait of Hormuz.1,2,3
~20%
Global methanol from Gulf (SA, Iran, Qatar, UAE)
~25%
Global nitrogen fertiliser exports (incl. ammonia)
~24%
Global sulphur production from Middle East
~31%
Global seaborne oil through Hormuz
Methanol is an extremely consequential molecule in supply chains. It is the direct feedstock for formaldehyde, acetic acid, formic acid and DMF, amongst many others. More indirectly (via methylamines with ammonia), it is essential to a large part of organic nitrogen chemistry. Formaldehyde itself is a direct Gulf methanol derivative, when methanol supply is disrupted or prices spike, formaldehyde availability and cost follow within days. Formic acid and acetic acid, the latter industrially produced by methanol carbonylation, face similar pressures.4
Chlorine and sodium hydroxide are co-produced in a fixed-ratio by energy demanding chlor-alkali electrolysis. Hydrochloric acid (HCl) is closely tied to this: it is a co-product of chlorination chemistry and a byproduct of the ethylene dichloride (EDC) and polyvinyl chloride (PVC) processes, concentrated in the Persian Gulf’s industrial complexes. The Middle East and Africa accounts for around 16% of global HCl supply, primarily serving oilfield services and regional industries, but disruptions to chlor-alkali capacity still have a global effect on market prices for chlorine, HCl and sodium hydroxide.5
Finally, a mention of sulphur and sulphuric acid. The Middle East produces approximately 24% of global sulphur, the primary feedstock for sulphuric acid manufacture via the contact process. Approximately 50% of seaborne sulphur trade passes through the Strait of Hormuz.3 Sulphuric acid plays a huge role in the chemical industry and is foundational to phosphate chemistry – relevant to some of the most routinely purchased products in any research or pharma catalogue.
Immediate Effect of Shortages
Each of these first-wave products has direct downstream consequences for fine chemical and pharmaceutical work.
| Gulf product constrained | Immediate downstream effects relevant to fine chemistry |
| Methanol / Formaldehyde | Formaldehyde-based resins; formic acid (HPLC mobile phase additive, peptide deprotection); acetic acid (solvents, AcOH mobile phases, coupling chemistry) |
| Ammonia | Ammonium salts and buffers (ammonium acetate, ammonium formate); organic bases (e.g. DIPEA); polar solvents (e.g. DMF) |
| Sulphur / Sulphuric acid | Phosphoric acid → phosphate buffers (PBS, phosphate-buffered media, among the highest-volume research and bioprocessing chemicals globally); various organosulphur compounds |
| HCl / Methyl Chloride | Silanes and chlorosilanes (surface chemistry, silica chromatography stationary phases, silicone chemistry); hydrochloride reagents throughout synthetic chemistry |
| Chlorine / Sodium Hydroxide | Water treatment across all industrial sites; PVC and packaging materials; bleaching agents; hydroxide and derived inorganic bases used as reagents and in pH adjustment throughout bioprocessing and fermentation |
| Ethylene / Ethylene Oxide | PEG polymers (PEGylation reagents, PEG-based resins for SPPS, PEG excipients in drug formulation); surfactants and detergents used in biochemistry; HDPE packaging throughout the supply chain |
Two of these deserve particular emphasis for research and pharmaceutical chemistry contexts. Phosphate buffers – prepared from phosphoric acid, itself produced using sulphuric acid – are the single highest-volume buffer system in biological and pharmaceutical research. A sustained sulphuric acid shortage does not make phosphate buffers immediately unavailable, but it does make them more expensive, and it creates supply uncertainty for products that researchers rarely think of as petrochemically linked.
Similarly, numerous organic bases, essential to countless chemical reactions, including SPPS and other amide couplings, trace their origins back to ammonia and often other Gulf-linked petrochemical products. For example, DIPEA (Hünig’s base) production involves the reductive amination of ammonia with acetone (also facing a squeeze).
Wave Two: Solvents and the Tools of Chemistry
As disruption creates upward pressure on costs across the board and essential materials, solvents and reagents are restricted in production, the cost of routine chemical processes increases. Compounds which are yet to face shortages in their direct feedstocks are still affected. Alongside the above shortages, supply chain issues work their way up through the solvents market, impinging on almost every aspect of chemistry.
DMF is of high concern. Its synthetic origin: methanol, ammonia and carbon monoxide involves products directly pressured in wave one. Ubiquitous in Fmoc solid-phase peptide synthesis, DMF is a major component of cost lines for peptide manufacturing. Increased DMF costs can lead to price increases here before there is any change in the availability of amino acid building blocks or resins.6 NMP, the popular alternative to DMF for SPPS and solvent for battery electrode processing has similar chemical origins and does not escape dependency on Gulf produced feedstocks.
Acetonitrile, essential to the smooth running of QC suites and analytical laboratories around the world, will face similar challenges. A byproduct of acrylonitrile manufacture via the Sohio process (feedstocks: propylene & ammonia), supply is somewhat inelastic, driven less by demand than it is by production of acrylonitrile. We’ve been here before: The 2008–9 “Great Acetonitrile Shortage” – when prices rose from ~$30 to over $100 per litre – was triggered by a combination of Chinese factory shutdowns and a hurricane in the Southern USA. Disruption in shipping through the Strait of Hormuz creates comparable pressures.7 Critically, pharmaceutical QC labs operating validated methods cannot substitute without regulatory notification, meaning they absorb cost increases in full with no short-term flexibility.
The validated method problem
Pharma QC labs cannot simply switch solvents when prices rise. Validated analytical methods require regulatory notification or prior approval to change. Labs running HPLC under an approved NDA or ANDA absorb acetonitrile or methanol price increases immediately and fully, with no short-term alternative.
The same constraint applies at CDMOs. Process solvents validated for a specific API campaign cannot be changed without process re-development and re-validation.
Feedstock Dependencies of Key Solvents
| Solvent | Primary use in research | Key feedstock(s) | Gulf exposure |
| Acetonitrile (MeCN) | HPLC mobile phase, LC-MS, crystallisation, synthesis | Acrylonitrile → propylene + ammonia (Sohio process) | High – propylene and ammonia both Gulf products |
| DMF (N,N-dimethylformamide) | SPPS (Fmoc), amide couplings, polar aprotic reactions, coatings | Dimethylamine + CO; dimethylamine from methanol + ammonia | High – methanol and ammonia both Gulf products |
| NMP (N-methyl-2-pyrrolidone) | SPPS alternative to DMF, polymer synthesis, cleaning, battery electrodes | γ-butyrolactone (from maleic anhydride or BDO) + methylamine (from methanol + ammonia) | High – two-step dependency on methanol and ammonia |
| DCM (dichloromethane) | Boc-SPPS, extractions, recrystallisation, paint stripping | Chlorination of methane or methanol; chlorine from chlor-alkali | Medium – chlor-alkali energy intensive and methanol, both Gulf products |
| Hexane / heptane / pentane | Normal-phase chromatography, extractions, crystallisation, GC calibration standards | Straight-run naphtha fractionation from crude oil refining | High – direct crude oil derivatives |
| Ethyl acetate | Column chromatography (with hexane), extractions, coatings | Ethanol + acetic acid; acetic acid from methanol via carbonylation | Medium – acetic acid chain back to methanol |
| IPA (isopropanol) | Cleaning, analytical work, chiral HPLC modifier, mobile phases | Propylene hydration; propylene from steam cracking of naphtha/propane | High – propylene from Gulf C₃ feedstocks |
| THF (tetrahydrofuran) | Polymer work, Grignard reactions, SEC/GPC, extractions | Butadiene → BDO → THF; or furfural route | Medium – BDO route links back to C₄ petrochemicals |
| DMSO | Compound storage/dissolution, cryoprotection, reaction solvent | Dimethyl sulphide from pulp processing; oxidation with sulphur chemistry | Medium – sulphur feedstock chain |
| Toluene | Swelling resins in SPPS, aromatic solvent for polymer work, coatings | BTX aromatics from catalytic reforming of naphtha | High – Gulf crude is dominant BTX source |
Wave Three: Building Blocks and the Research Catalogue
A sustained disruption of months rather than weeks begins to affect the synthetic route of research chemicals themselves. Direct shortages of materials higher and higher up the routes of synthesis dramatically affect availability, compounding the increased costs of production outlined above.
For example, Fmoc amino acids are reliant on Fmoc-Cl (fluorenylmethyl chloroformate) for protection. Fmoc-Cl is made from fluorenylmethanol and phosgene, phosgene from chlorine and CO. The chlorine route connects back directly to chlor-alkali production now under pressure. There may be a lag as the shortages work their way through the supply chain, but the consequences arrive eventually.
The problem is further demonstrated in the case of fluorinated building blocks, key to medicinal chemistry, agrochemical development and materials research. They ultimately require hydrogen fluoride (HF) at some stage of their production. HF is manufactured from fluorspar and sulphuric acid and the sulphuric acid links back through sulphur, of which 50% of the seaborne trade passes through Hormuz. Eventually cost pressures here will pass onto fluorination chemistry and these fluorinated building blocks.
A final example: polyethylene glycols (PEGs) and their derivatives. PEGylation agents, resins for SPPS, PEG excipients and surfactants, ADC and PROTAC linkers – are ultimately made from ethylene oxide, itself sourced from cracking of crude oil or natural gas liquids. Eventually price pressure on these from disruption in the Persian Gulf leads to further cost increases for these PEG products.
So, the overall effect is not a sudden availability of any given catalogue item (although eventually certain items may be in short supply), but rather broad, simultaneous repricing of the costs of synthetic chemistry. Solvents, reagents, building blocks and analytical consumables all suffering from immediate, and then creeping, inflation as shortages work through supply chains. For academic groups on fixed grants, CROs pricing fixed-fee contracts, and CDMOs managing campaign economics, this kind of systemic cost inflation is harder to manage than any single shortage, because there is no single substitution that resolves it.
