Usage

General Description

DI-N-BUTYLDIPHENYLTIN is an organotin compound that is used as a catalyst in various chemical reactions, suchjson halogenation and hydrolysis. It is commonly used as a stabilizer for PVC and as a biocide in marine anti-fouling paint. However, due to its toxicity and environmental concerns, its use has been restricted in many countries. It has been found to be harmful to aquatic life and can have toxic effects on humans if ingested or inhaled in large amounts. Therefore, careful handling and disposal of products containing di-n-butyl diphenyltin is necessary to minimize its impact on the environment and human health.
