Description of key information
2,2'-azobis(2,4 -dimethylvaleronitrile) is an unstable substance to hydrolysis, photolysis and thermolysis due to its azo group. Because of this instablility the substance is used as radical initiator in polymerization reactions.
The available data according to OECD 111 study indicate a half-life of approx. 650 h at 25 °C. Different potential transformation products from the hydrolysis are identified using the QSAR Toolbox v4.2 simulation. Additionally, the substance undergoes thermal transformation. According to company data the transformation products 2,4 -dimethylpentanenitrile (CAS# 69975 -94 -6) (7 %), 4 -methyl-2 -methylenepentanenitrile (7 %) and 2,3 -diisobutyl-2,3 -dimethylsuccinonitrile (CAS# 80822 -82 -8) (85 %) are formed during the reaction.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
