Description
Liquid; [Hawley] Colorless liquid; [MSDSonline]
Sources/Uses
Used as a biocide in paints for ships and fishnets; [ChemIDplus] Used as a reducing agent for the conversion of alkyl halides to hydrocarbons, a veterinary anthelmintic for poultry, and an intermediate to make other butyltin compounds; Use as a marine biocide is being phased out globally due to toxicity to aquatic organisms.
