Crotonnitrile, known under the molecular formula C4H5N, stands out for its simple yet reactive structure. With a density of 0.806 g/cm3, this colorless liquid appears in various synthesis and extraction processes. Its HS Code, a reference for customs and shipping, sits at 2926909090, guiding international trade. The nitrile group, along with the trans-configuration on its double bond, determines much of this chemical’s properties and behavior in reactions.
With increased demand for pharmaceutical and agrochemical ingredients, crotonnitrile from China commands attention. China’s suppliers lead global exports, offering competitive factory price and large-scale OEM production. Many manufacturers provide free samples and MOQ flexibility, giving buyers room to confirm quality before scaling up. Quotes come fast, often supported by REACH, ISO, and SGS certifications. Buyers can choose between FOB or CIF terms based on port requirements or freight forwarding policies. Inquiries for custom packing, halal, and kosher-certified batches are rising as global user needs shift.
Crotonnitrile’s use spans sourcing raw materials for pharmaceuticals to generating intermediates in specialty chemicals. Its role as a building block stretches from solvent blends to polymer manufacturing. This versatility comes with strict attention to grade, purity, and batch specifications—especially for solution preparation in liter-scale laboratories and plants. Customers often request material safety data sheets (MSDS), detailed TDS, and even full REACH registration proofs to support new product registrations and regulatory audits.
Though crotonnitrile supports innovation, it brings significant hazards. Classified as harmful if inhaled or ingested, the chemical requires robust ventilation, specialized PPE, and secure storage. Knowledge of its hazardous nature isn’t just a compliance box; importers and users must act on SDS data, employee training, and secure transportation protocols—especially across international boundaries. For companies shipping from China to the EU or US, proper labeling, hazard declarations, and documentation remain critical. Labs and factories turn to SGS for independent testing, ensuring no shortcut puts health or policy at risk.
Supply chains for crotonnitrile have tightened with global policy changes. New customs checks, REACH enforcement, and export controls add challenges for both China suppliers and international buyers. Bigger buyers now demand traceable sourcing, ISO audits, and eco-complaint packaging—moving past simple price comparisons. News of stricter rules pushes many to build deeper relationships with reputable manufacturers, reducing supply risk and safety uncertainty. For experienced chemists and business owners, policy tracking matters just as much as technical data.
For those seeking crotonnitrile today, sending an inquiry means sharing application, desired quantity, and required certifications upfront. Clear communication on MOQ, required documentation (SGS, HALAL, KOSHER), and logistics helps avoid delays. Manufacturers favor buyers who understand quote comparison, product traceability, and the real cost of regulatory lapses. With more markets demanding full certification, OEM suppliers who deliver custom labeling and robust technical support see the highest repeat business.
