Tributyltin chloride is an organotin compound with the formula (C<sub>4</sub>H<sub>9</sub>)<sub>3</sub>SnCl. It is a colorless liquid that is soluble in organic solvents.
The compound is prepared by a redistribution reaction by combining stannic chloride and tetrabutyltin:
Tributyltin chloride hydrolyzes to the oxide [(C<sub>4</sub>H<sub>9</sub>)<sub>3</sub>Sn]<sub>2</sub>O
Tributyltin chloride is used as a precursor to other organotin compounds and reagents, such as tributyltin hydride.
