Description :

Overview of AIBN (Azobisisobutyronitrile)

AIBN (Azobisisobutyronitrile) is a chemical initiator used primarily in polymer synthesis, radical reactions, and organic chemistry. It is renowned for its capacity to create free radicals after the decomposition of heat. AIBN is extensively used for the process of initiating polymerisation, as well as radical-mediated organic transformations and in materials science research.

The compound is an ethereal white or pale yellow powder with distinctive characteristics. The process of thermal decomposition, which generates nitrogen gas and two isobutyronitrile radicals, provides the ability to control radical activation for a variety of chemical procedures.

Other related products include benzoyl peroxide and other radical initiators that are used in organic chemistry as well as polymer chemical synthesis.
