Acetonitrile, often called R5 by industry insiders, packs a punch in both labs and factories. Its chemical formula is C2H3N, with a molecular weight of 41.05 g/mol. Colorless, volatile, and with a faint but distinct odor, acetonitrile stands out for its high polarity. This feature allows acetonitrile to dissolve a broad range of organic and inorganic compounds. I’ve seen research institutions depend on its purity, especially in high-performance liquid chromatography (HPLC) analysis. Specific density lands at about 0.786 g/cm3, and it holds up at a boiling point just over 81°C. The HS code for acetonitrile, 2926909090, signals buyers to the chemical’s exact import-export class, paving smoother shipping from China-supplying manufacturers.
China dominates the acetonitrile landscape as both a raw material hub and a finished-product exporter. Factories across major Chinese provinces have ramped up output, balancing raw materials sourcing and optimized manufacturing routines. In my work with purchasing teams, Chinese suppliers often offer factory pricing well below what’s seen in Western markets. The CIF and FOB terms for global shipment make large liter orders doable, even when dealing with small inquiry minimum order quantities (MOQ). Asking for a quote often means access to free samples and live support with technical data sheets (TDS) and REACH/SDS documentation, which helps make purchasing decisions both smarter and safer.
While acetonitrile opens doors to innovation in pharmaceuticals, paints, plastics, and electronics, it comes with risks. MSDS and SDS information spell out the hazards: harmful if inhaled, flammable, toxic if ingested. Classification as a hazardous material means transport and storage demand attention—a lesson I learned checking compliance during an ISO audit. Responsible buyers always check for SGS test reports, as well as certificates covering halal, kosher, and OEM standards. Demand for REACH-certified material ticks up every year, especially across Europe.
Bottle by liter or delivered in bulk drum, acetonitrile material specs can make or break a process. Concentration, water content, purity grade, and possible trace metal content all affect the result. Technical departments rely on these details to select the right product for HPLC solvents, syntheses, or cleaning agents. Manufacturers who keep their eye on batch-to-batch consistency build long-term relationships with end users. Today, more buyers ask for ISO-certified material and want assurance the product fits their exact application—be it pharma, agrochemicals, flavors, or another use. Tracking down a compliant manufacturer in China becomes easier, as more suppliers promote certifications and testing reports up front on every quote.
Markets for acetonitrile stay busy as global demand grows alongside pharmaceutical and electronics industries. End users keep a close watch on policy changes, especially those related to hazardous material transport and environmental restrictions. Policy shifts on chemical import can affect lead time, so staying informed pays off. As volatility threatens some regions, savvy buyers turn to backup suppliers and look for diversified stock close to ports like Shanghai and Qingdao. Informed negotiation with suppliers—asking for clear documentation and regular policy updates—makes business smoother. Keeping pace with the news means fewer surprises and better deals down the line.
