Every lab worker who handles analytical chemistry work comes across acetonitrile, but only some ever use its disotopic purity variant. The difference isn’t academic. Disotopic purity brings a level of consistency that matters in nuclear magnetic resonance studies, chromatography, and advanced synthesis. The stability this brings isn’t hype – it reduces background interference, helps clean up spectra, and saves real money through reduced sample loss.
Look anywhere in the world of chemicals, China stands out as a major supplier for acetonitrile disotopic purity. Years of production experience, intense investments in process control, and regulatory certifications like ISO or SGS drive this position. Factory-direct sales keep the price per liter affordable. Manufacturers work directly with both bulk-end users and research labs to figure out minimum order quantities (MOQ), negotiate purchase terms like CIF or FOB, and ensure documentation such as SDS, TDS, and MSDS align with EU REACH or local requirements.
Not all acetonitrile is created equal. Disotopic purity refers to isotopic labeling – often including deuterated acetonitrile (CD3CN) – which brings reliable, traceable purity standards. Its molecular formula is C2H3N for regular, but with deuterium, you find CD3CN. This gives it a molecular weight of around 45.08 g/mol, specific density close to 0.786 g/cm³, and brings new advantages in MS analysis or NMR. Structure-wise, the triple bond between carbon and nitrogen in acetonitrile makes it particularly stable.
It's no secret that hazardous raw materials need respect in the lab. Acetonitrile – even in high purity – gives off vapors that irritate eyes and lungs. Anyone handling should check MSDS and wrap up all open containers fast. Labs store this chemical in cool, ventilated rooms, with liter bottles or bulk drums clearly labeled with the HS code 2926909090. Despite global moves to green solvents, data shows over 90% of high-end LC-MS systems run acetonitrile-based mobile phases because of its performance and broad supply base. Certification from organizations like REACH, ISO, or third-party labs, plus evidence of HALAL or KOSHER certification, helps users choose safe and accepted suppliers.
Purchasing works much like any other industrial supply. Buyers send inquiries directly to China-based manufacturers or agents. Some companies provide free samples for testing new lots, and prices reflect current raw material inputs, shipping cost, and volume – no mystery markups. Minimum order quantities vary; research buyers might need just one or two liters, while industry pulls in pallets of drums at a time. Payment terms (CIF, FOB), quote speed, and OEM production options remain important for real customers who care more about lead times and after-sale support than shiny catalogs.
News in the acetonitrile space means updates on supply policies, shifts in export controls from China, or upgrades in ISO certification. Major buyers want assurance of SGS inspection, safe transit, proper labeling, and both REACH + SDS compliance. For anyone building a lab or production line, asking about current specifications, price trends, application support, and the latest compliance policy turns a purchase into a partnership – not just a transactional end note.
