Diethyltin dichloride

Description:

Diethyltin dichloride, with the CAS number 866-55-7, is an organotin compound characterized by its two ethyl groups and two chlorine atoms bonded to a central tin atom. It appears as a colorless to pale yellow liquid with a pungent odor. This compound is known for its applications in various fields, including as a stabilizer in PVC production and as a biocide in antifouling paints. Diethyltin dichloride is soluble in organic solvents but has limited solubility in water. It exhibits toxicity, particularly through inhalation or skin contact, necessitating careful handling and appropriate safety measures. The compound can undergo hydrolysis in the presence of moisture, leading to the formation of diethyltin oxide and hydrochloric acid. Its reactivity is attributed to the tin-chlorine bonds, which can participate in various chemical reactions, including nucleophilic substitutions. Overall, diethyltin dichloride is a significant compound in industrial applications, but its environmental and health impacts require consideration and regulation.
