But-3-Enenitrile falls among specialty nitrile compounds in chemical manufacturing, recognized for its formula C4H5N and linear structure: CH2=CH-CH=CH–CN. Known by its HS Code 2926909090, it serves as a building block for pharmaceuticals, intermediates, and organic synthesis. The molecular weight stands at 67.09 g/mol, and with a specific density around 0.85 g/cm³ at 20°C, this colorless to pale yellow liquid brings distinct reactivity owing to its double bond and nitrile group.
China’s chemical suppliers and manufacturers offer But-3-Enenitrile both in bulk and laboratory grades, with global shipping options like CIF and FOB. Locally, price per kilogram or per liter trends much lower from factory-direct sources compared to intermediaries. Many plants in Jiangsu and Zhejiang regions hold ISO 9001, SGS, and OEM certification. For international buyers, registration under REACH and complete MSDS/SDS documentation comes essential for customs clearance and safe transport. Halal and kosher certificates are available for specialized markets. Most suppliers require a MOQ starting from 100 kg or 200 liters, with free samples often available for R&D.
But-3-Enenitrile needs to meet strict purity criteria, often ≥98% by GC, and shows boiling point near 134°C. As a hazardous raw material, it carries warning labels under GHS—flammable liquid, harmful if inhaled or swallowed, and major skin or eye irritant. Proper PPE matters: chemical-resistant gloves, goggles, and fume hoods keep operators safe. In my own experience programming for chemical importers, prompt access to the supplier’s TDS and MSDS solves headaches for EHS officers during audits. Safe transport follows UN 1993 for flammable liquids, ensuring insurance coverage in global logistics.
But-3-Enenitrile acts as an intermediate in drug synthesis, polymers, and specialty coatings. Downstream buyers include pharmaceutical, resin, and fine chemical factories. Use guidelines hinge on purity, low water content, and full documentation, not just cost-per-ton. Firms I’ve advised press for REACH-registered, SGS-tested, and ISO-audited material, especially after shifts in EU chemical safety policy. Those with halal and kosher needs find factory certifications ensure raw material traceability.
Getting a quote or inquiry to a Chinese chemical supplier looks straightforward, but attention to detail pays off. Always request COA, MSDS, and confirmation of ISO, REACH, and certifications before PO. Ask whether free samples come as part of the contract or get deducted from bulk purchase. For sensitive uses, insist on full batch traceability and TDS. CIF Shanghai or FOB Ningbo usually offers the best mix of price and risk management, based on freight trends. Larger buyers sometimes negotiate yearly delivery with price locks, preventing market swings from hitting production budgets.
Policy changes in China and new chemical lists in the EU and US shape global sourcing. Factories with updated REACH status remain in highest demand. From talking with procurement teams, the main struggles hit when specs or certification lag behind the growing demands for transparency. Responsible suppliers respond by posting certification updates, lab test results, and TDS on their corporate sites for all clients and regulatory inspectors. Factories keeping pace with new policy changes secure repeat business and stronger supply chain trust, benefitting safety and long-term pricing.
