Tetrabutyltin is a precursor to tributyltin and dibutyltin compounds. By the redistribution reaction with tin(IV) chloride it forms tributyltin chloride and dibutyltin chloride. These compounds are starting materials for a wide range of organotin compounds used as stabilizers for PVC and as biocides, fungicides, wood preservatives, and (historically) marine anti-biofouling agents.[4]
