[Chemical Properties]

white crystalline powder
[Uses]

4,4’Azobis(4-cyanovaleric Acid) is a water soluble azo initiator usded in radical polymerization process of vinyls, acylamides, styrenes as well as other polymers.
[Uses]

4,4'-Azobis(4-cyanovaleric acid) is used as a free radical imitator in polymer synthesis such as polyvinyl chloride, polyacrylonitrile, polyvinyl alcohol and synthetic fibers. It is utilized for both heterogeneous and homogenous free-radical polymerizations, and as an initiator in reversible addition-fragmentation chain transfer polymerization (RAFT). It is also used as a blowing agent for plastics and elastomers.
[Flammability and Explosibility]

Notclassified
[Biochem/physiol Actions]

4,4′-azobis(4-cyanovaleric acid) is an azo-initiator that induces lipid peroxidation of sunflower oil.
[Safety Profile]

Moderately toxic byintraperitoneal route. When heated to decomposition itemits toxic vapors of NOx.
