Azobis(Isobutyronitrile), often identified as AIBN, stands as a cornerstone initiator in polymer chemistry. Its molecular formula, C8H12N4, and specific density near 1.11 g/cm3 make it a staple for anyone working with free radical polymerization. On the structure front, you find a molecule featuring a central azo group connected to isobutyronitrile units on each end. Its HS Code, 2927000090, helps classify it for customs and trade purposes. This solid, white powder dissolves well in many organic solvents, turning it into a go-to raw material for making plastics, adhesives, and coatings.
AIBN comes from chemical plants across China, which leads the global scene in both volume and price advantage. When searching for suppliers, companies focus on keywords like 'chemical-buy', 'manufacturer', and 'factory price' to secure cost-effective deals. The market sees plenty of bulk deals, and quantity discounts turn up often for orders exceeding the MOQ—minimum order quantity—that tends to start around 25 kg. Direct from factory, CIF and FOB terms give buyers flexibility in shipping and insurance. For those needing regulatory paperwork, Chinese suppliers frequently provide ISO, SGS, and REACH reports, plus TDS, SDS, and even OEM services for tailored blends.
Anyone who works with AIBN learns quickly to keep safety top-of-mind. This chemical brings a hazard classification as harmful, and improper handling can pose serious risks. Manufacturers supply Material Safety Data Sheets (MSDS) and updated Safety Data Sheets (SDS) in multiple languages. These lay out personal protective equipment, safe handling, spill protocols, and disposal methods. For buyers facing stringent audits or looking to sell downstream, REACH registration, ISO9001 certification, and third-party test reports from SGS add confidence. Some factories now go the extra mile and offer certifications like halal and kosher, opening the door for customers seeking extra assurances.
With a high level of purity offered—usually upwards of 99%—AIBN meets the requirements of demanding industries. Labs and plants use it as an initiator, and you'll see it show up in the synthesis of specialty polymers, rubber, and some pharmaceutical intermediates. Liters of solution or raw solid form get shipped out, accompanied by analysis documents showing compliance to agreed specs. Some buyers request printable quotes and prefer payment methods that match global commerce, like CIF or FOB, for transparent deals.
From experience working in specialty materials purchasing, sourcing AIBN from Chinese suppliers often brings up two big practical questions: can the factory prove full compliance, and do they ship with consistency in both product and paperwork? The leading firms now offer free samples, batch documentation, and a direct line for technical support. Real transparency about raw materials and hazardous nature helps buyers stay on the right side of regulatory checks. Security in the supply chain comes from traceable documentation, responsive customer support, and a solid reputation for meeting delivery agreements. In a market where news about safety policies or REACH updates can swing buying decisions overnight, reliable factories—those posting all current certifications and policies online—become long-term partners, not just vendors.
