Aibn (78-67-1) (C8H12N4)

AIBN (Azobisisobutyronitrile) is an organic azo compound with the chemical formula C8H12N4 and molecular weight 164.21 g/mol. It appears as a white crystalline powder. It is insoluble in water but soluble in organic solvents such as alcohols and ketones. It is thermally unstable and decomposes upon heating to generate free radicals and nitrogen gas. It should be handled carefully and stored under controlled temperature conditions.
In terms of uses and applications, AIBN is widely used in the polymer industry as a free radical initiator for polymerization of vinyl monomers such as acrylates, methacrylates, styrene, and acrylonitrile. It is essential in producing plastics, resins, coatings, and adhesives. In the chemical and pharmaceutical industries, it is used in organic synthesis for radical reactions and intermediate formation. It is also applied in laboratory research for controlled polymerization studies and material science development.
