Used as a radical initiator in polymer chemistry, particularly in the controlled polymerization of vinyl monomers. It decomposes upon heating to generate free radicals that initiate chain reactions, making it valuable in the synthesis of specific polymers with narrow molecular weight distributions. Also employed in organic synthesis for azo coupling reactions and as a reagent in the preparation of functionalized aromatic compounds. Its stability at room temperature and predictable decomposition behavior make it suitable for laboratory-scale reactions requiring precise initiation control.
