PRODUCT INTRODUCTION
description
Dibutyltin oxide is an organotin compound. It is used mainly in organic synthesis. Tin is a chemical element with the symbol Sn and atomic number 50. It is a natural component of the earth's crust and is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide. (L307, L309, L312)
