The toxicities of tributyltin and triphenyltin derivatives compounds are comparable to that of hydrogen cyanide. Furthermore, tri-n-alkyltins are phytotoxic and therefore cannot be used in agriculture. Depending on the organic groups, they can be powerful bactericides and fungicides. Reflecting their high bioactivity, "tributyltins" were once used in marine anti-fouling paint. In contrast to the triorganotin compounds, monoorgano, diorgano- and tetraorganotin compoun… getting rid of musty odorsWitrynaOrganotin substances (organotins) are tin compounds having 1,2,3 or 4 organic groups attached and are designated as mono-, di-, tri- or tetra-organotin depending on the number of tin-carbon bonds in the molecule. ...
