2,2’ - Azobisisobutyronitrile - 78-67-1

Key Functions: Industrial / Manufacturing

2,2’-Azobisisobutyronitrile is an azo-containing organic compound that is used as a blowing agent for elastomers and plastics and as an initiator for free radical reactions. It is also a vinyl polymerization catalyst and a curing agent for unsaturated polyester resins. 2,2’-Azobisisobutyronitrile is an indirect food additive (21 CFR § 175.105, 21 CFR § 176.170, 21 CFR § 177.2420) (PubChem 2021). ToxServices assessed 2,2’-azobisisobutyronitrile against GreenScreen® Version 1.4 (CPA 2018b) following procedures outlined in ToxServices’ SOPs (GreenScreen® Hazard Assessment) (ToxServices 2020).
