Description and Uses

Dibutyltin dichloride is used as an organotin intermediate. It serves as heat and light stabilizer for polyvinyl chloride plastics. It is also used in the preparation of methyl 2-(methoxycarbonylmethyl)-5-iodobenzene by reacting with 2,5-diiodobenzoic acid. It acts as an esterification catalyst and a veterinary vermicide and tapeworm remedy. Further, it is used as ion exchange agent, process regulators and processing aids.
