What is the use of AIBN? Is it toxic?

AIBN is widely used as a free radical initiator. It has labile carbon-nitrogen covalent bond which undergoes homolytic scission under thermal, chemical or photochemical conditions producing free radicals. They are useful in many reactions like halogenation, polymerisation of vinyl monomers, grafting reactions, curing of rubbers and unsaturated polymers and cross-linking of polyolefins. AIBN is self reactive substances, it has an acute toxicity(Oral and Inhalation), it is toxic if swallowed.
