Azobis(isobutyronitrile)丨CAS 78-67-1 (commonly abbreviated as AIBN) is a widely used free radical initiator in organic synthesis and polymer chemistry. It is a white, crystalline solid known for decomposing to produce nitrogen gas and reactive free radicals, which can initiate various chain reactions.
Key Applications of Azobis(isobutyronitrile)丨CAS 78-67-1
1. Polymerization Initiator
AIBN is extensively used to initiate free-radical polymerizations of monomers such as:
● Styrene
● Acrylonitrile
● Vinyl acetate
● Methyl methacrylate (MMA)
It is especially useful in producing plastics, rubbers, and resins due to its clean decomposition and ability to generate radicals under mild conditions.
2. Organic Synthesis
In organic chemistry, AIBN is employed in:
● Radical addition reactions
● Chain transfer reactions
● Hydrogen atom abstraction reactions
Its role is crucial in processes like thiol-ene and azide-alkyne click chemistry.
3. Foaming Agent
Upon decomposition, AIBN generates nitrogen gas, making it useful as a blowing agent for producing porous structures in plastics and rubber.
4. Laboratory and Industrial Research
AIBN is widely used in R&D labs and industrial-scale synthesis for designing novel polymers, drug delivery vehicles, and radical-based materials.
