Innovation in chemistry often hinges on the availability of precise and reliable chemical compounds. 2,2'-Azobis(2-methylpropionitrile), commonly referred to as AIBN, is one such compound that has become indispensable in various industrial and research applications. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of AIBN, dedicated to providing materials that drive progress across numerous sectors.

AIBN is characterized by its chemical formula C8H12N4 and its CAS number 78-67-1. It typically appears as a white crystalline powder, with a melting point in the range of 102-104 °C (with decomposition). Its solubility in organic solvents like methanol, ethanol, and acetone, coupled with its insolubility in water, dictates its handling and application parameters. The primary utility of AIBN lies in its function as a radical initiator. Upon heating, it decomposes to release nitrogen gas and two 2-cyano-2-propyl radicals. These radicals are key to initiating free-radical polymerization reactions.

The effectiveness of AIBN as a polymerization initiator is evident in its widespread use. It is a critical component in the synthesis of polymers such as polystyrene, polyvinyl chloride, and polyacrylates. Its controlled decomposition makes it an excellent choice for the polymerization initiator for styrene applications, ensuring uniform polymer chains and desired material properties. Furthermore, AIBN serves as a foaming agent for plastics, contributing to the creation of lightweight, cellular materials used in a variety of consumer and industrial products.

Beyond its role in polymer production, AIBN is also a valuable organic synthesis intermediate. Its ability to generate radicals facilitates various organic transformations, aiding in the synthesis of complex molecules. The inherent azo compound advantages, such as cleaner decomposition byproducts compared to peroxides, further enhance its appeal for precise chemical syntheses.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of using high-purity AIBN to achieve optimal results. Whether it’s for initiating polymerization reactions, acting as a foaming agent, or serving as an intermediate in organic synthesis, the quality of AIBN directly impacts the outcome. Our commitment to providing premium chemical solutions ensures that our clients can confidently leverage AIBN’s versatile properties to drive their own innovations, from advanced materials to novel chemical compounds.
