(2E)-But-2-enenitrile, also known as crotononitrile, comes up often in chemical circles for its practical role as a raw material in organic synthesis. Its molecular formula is C4H5N. The CAS Number for easy tracking and sourcing: 4786-20-3. This nitrile boasts a structural layout with a double bond conjugated to the cyano group, offering unique reactivity in the production of intermediates for pharmaceuticals, agrochemicals, and specialty polymers.
The specific density clocks in at around 0.805 g/cm3 (25°C). It appears as a clear to slightly yellow liquid at room temperature, with a molecular weight of 67.09 g/mol. For buyers, these specs matter for both storage and application. Typical HS Code for import-export tracking: 2926909090. This detail helps streamline customs clearance and cross-border trade compliance.
When you look for reliable sourcing, China stands out with a developed supply chain, factory-directed pricing, and extensive production scale. Manufacturers from China supply (2E)-But-2-enenitrile worldwide, supporting requests as low as single-litre samples to larger drum shipments. Direct factory price reduces the costs for downstream producers, especially under terms like CIF and FOB.
Procurement teams ask for material safety data sheet (MSDS), SDS, TDS, and technical support before approving any order. Certified Chinese suppliers carry ISO, SGS, REACH compliance, and often meet niche requirements like halal or kosher status. These guarantees make a difference for buyers running audits or needing OEM-labeled products for sensitive use cases. My own experience shows that having documentation in place reduces delivery holdups and builds trust with regulatory agencies downstream.
This compound counts as hazardous. Good ventilation, gloves, and eye protection in the workplace become standard practice based on the parameters in the material safety data sheet. Exposure risks include irritation upon inhalation or skin contact. Labels must clearly display hazard statements as outlined by GHS standards. Always transport and store in tightly sealed containers away from heat sources. I recommend building a strong relationship with suppliers who provide up-to-date SDS and handle shipping lines with compliance top of mind.
Most suppliers require a minimum order quantity (MOQ)—typically from 1L to multiple kilograms. For fresh buyers, requesting a free sample often helps verify quality before a large purchase. News circulates regularly on policy updates, such as EU REACH registration or export restrictions, so it pays to keep an eye on supplier bulletins. Transparent CIF or FOB quotation gives buyers control over costs and helps plan budgets.
(2E)-But-2-enenitrile goes into the synthesis of niacin, crop protection ingredients, and specialty polymers. Its demand often tracks with the development of new generic drug APIs and next-generation agrochemicals. News of regulatory changes and approvals impacts not just price, but also the choices you get in the market. Having trusted suppliers who keep pace with industry standards and new certifications helps businesses stay competitive and minimize regulatory risk.
