4-Chlorobutyronitrile appears as a clear or light yellow liquid, best known as a raw material with considerable clout in pharmaceutical, agrochemical, and specialty chemical production. Its structure, C4H6ClN, houses a chlorine and nitrile group, making it a versatile building block. With a specific density around 1.06 g/cm³, it slides seamlessly into various organic syntheses. Its CAS number, HS Code 292690, and molecular formula tick all the boxes for regulatory needs in both China supply chains and international purchase agreements.
Getting 4-Chlorobutyronitrile straight from a trustworthy chemical supplier or manufacturer often spells the difference between project success and wasted time. Reliable plants, especially those under ISO, SGS, or REACH certification, ensure both safety and consistency. I have seen folks run into trouble when buying on price alone—the headache that follows from impure or misrepresented batches can stall entire production lines. China-based manufacturers usually offer some of the best factory prices, competitive CIF and FOB, and ship with OEM and halal or kosher options.
With a boiling point around 192°C and stable reactivity profile, this material adapts easily to different processing environments. Chemists value 4-Chlorobutyronitrile for its predictability during complex transformations, as it rarely surprises in strongly basic or mildly acidic conditions. Many fields count on this reliability, especially when scaling up for kilo-lab or factory production. The material’s MSDS outlines common risks such as skin and eye irritation, emphasizing the importance of gloves, goggles, and solid ventilation during handling.
The best suppliers put safety first. When I evaluate a new producer, the first thing I look for is access to SDS, TDS, and lab-scale sample reports. These documents spell out exactly how hazardous or harmful the raw material could be, flagging risks before they reach the lab or shop floor. Factories certified under ISO 9001 and audited for halal or kosher standards support not only compliance but also a wider market, which matters if you ever export or serve clients with strict sourcing policies.
Market rules keep changing, from reach regulations in the European Union to regular shifts in China’s export policies. Even small players now face questions about MOQ, quote formats, and permitted end uses. Detailed inquiry responses and free samples let buyers test for purity and performance before committing to large MOQs or custom orders. Certification by SGS or independent labs further reduces procurement risk, especially in new market launches or policy-sensitive applications. As news about chemical safety moves quickly, staying ahead with updated certifications and proactive documentation pays off in client confidence.
Many of the world’s active pharmaceutical ingredients and crop-protection agents rely on intermediates like 4-Chlorobutyronitrile. Those with experience—myself included—know the value in a stable, well-documented supply chain. Factory-direct purchasing, supported by a thorough quote and SDS, takes much of the guesswork out of scaling or switching suppliers. Whether ordering by the liter or ton, focusing on certified quality over simple raw materials price creates long-term value and keeps customers coming back.
