But-2-enenitrile, known by its molecular formula C4H5N, stands as a vital raw material in multiple industrial streams. This clear, colorless liquid, sometimes referred to as crotononitrile, carries specific density around 0.810 g/cm³ and can be recognized by its CAS No. 4786-20-3. But-2-enenitrile draws attention for its unique nitrile group, bringing reactivity that suits organic syntheses in the pharmaceutical and agrochemical sectors. Factories in China supply this chemical globally at factory price, backed by ISO or SGS certification to support traceability and safety for buyers.
This molecule features a nitrile group bonded to a butene backbone, making it a valuable building block for synthesizing more complex chemicals. It presents a boiling point near 124°C and flashes at about 20°C, adding to safety handling requirements. Hydrocarbon structure ensures solubility in organic solvents and limited solubility in water. HS Code 2926909090 classifies it for customs and import/export procedures, and manufacturers provide tech data sheets (TDS), safety data sheets (SDS/MSDS), and reach compliance for buyer reference.
Industries reach for but-2-enenitrile for production of intermediates like pharmaceutical actives, polymers, pesticides, and specialty chemicals. Synthesis of heterocyclic compounds relies on this liquid as a key reactant. R&D labs explore new pharmaceuticals with but-2-enenitrile derivatives, benefitting from its structural flexibility. China suppliers maintain MOQs for bulk customers and offer CIF, FOB, and FCA pricing to match various shipping and logistics needs. Certified batches with halal and kosher approval widen the potential customer base, especially when downstream applications touch on food or pharmaceutical domains.
Safe handling stands front and center here. Labels point out flammable and harmful characteristics—procedure demands strict use of PPE in manufacturing and research settings. Storage guidelines suggest cool, ventilated warehouses with limited ignition sources. But-2-enenitrile carries inhalation and skin absorption risks. Factories ship it with a robust MSDS, hazardous materials labeling, and transportation documentation, as international policies demand. Customers checking for REACH and global GHS compliance find these certifications from leading China manufacturers, often verified by third-party audits and regular testing under ISO or SGS standards.
China's chemical plants open direct purchasing channels with buyers worldwide. Typical process begins with inquiry—buyers request samples or quotations (including free sample if available). Price lists come with options for CIF (Cost, Insurance, Freight) or FOB (Free on Board), determined by the buyer’s preference. Factories communicate specific batch specs, HS Code details, and regulatory compliance up front. Minimum order quantity (MOQ) is usually set, but factories negotiate on large runs or repeat business. Custom OEM labeling or documentation suits downstream users, all backed by raw material traceability and official certification (halal, kosher, ISO).
Global policies keep evolving, particularly for hazardous raw materials. China suppliers invest in sustainable production, update SDS sheets, and provide TDS in English. Buyers tracking policy and news benefit from regular supplier communication—real-time updates on price shifts, safety changes, or new certification developments. Demand grows in both established markets and emerging regions, spurred by pharma demand and new synthesis pathways. Manufacturers who keep pace with REACH and ISO standards gain trust, ensuring raw material purchases remain smooth and fully compliant for every customer.
