"Trialkyltin compounds" refer to a group of organotin chemical compounds where tin is bound to three alkyl groups, which are chains of carbon atoms with hydrogen atoms attached. A general formula for these compounds is (CnH2n+1)3Sn, where n represents the number of carbon atoms in each alkyl chain. Examples include triethyltin (C2H5)3Sn and tripropyltin (C3H7)3Sn. These compounds have been used in various industrial applications, but their use has raised environmental and health concerns due to their toxicity.
