PRODUCT INTRODUCTION
description
Tetrabutyltin is an organotin compound. It is the starting material of the tributyltin and dibutyltin compounds, which are used as stabilizers for PVC, biocides, fungicides, and anti-biofouling agents. 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.
