Application

Dibutyltin dichloride serves as a multifunctional organotin intermediate with several applications across various industries. Primarily, it is used as a heat and light stabilizer in the production of polyvinyl chloride plastics, ensuring the longevity and durability of these materials. Additionally, it plays a critical role in chemical synthesis, such as in the preparation of methyl 2-(methoxycarbonylmethyl)-5-iodobenzene from 2,5-diiodobenzoic acid. Beyond its industrial uses, dibutyltin dichloride functions as an esterification catalyst and is employed in veterinary medicine as a vermicide and remedy for tapeworm infections. It also finds use as an ion exchange agent and in various process regulation and support applications. Its properties, including solubility in organic solvents and low volatility, make it an effective choice for these roles, although care must be taken due to its flammable nature and pungent odor.
