Tributyltin oxide is primarily used as a reference compound in research related to wood preservatives and antifouling agents. Its historical applications include use in marine coatings to prevent biofouling on ships and in wood preservation to protect against fungal and insect damage. However, due to its severe environmental toxicity and bioaccumulation potential, its use is now heavily restricted in many countries. Researchers may also utilize this compound in studies investigating the mechanisms of organotin toxicity and its effects on aquatic ecosystems.
