Documented Uses

• The lower trialkyltins from trimethyl to tri-n-pentyl show high biological activity. The trimethyltins are highly insecticidal. However the triorganotins that are most useful as biological control agents are the tributyltins, triphenyltins, and tricyclohexyltines.
• Byproduct of methyltin production
• Triorganotin chlorides ... are generally prepared by Kocheshkov redistribution from the crude tetraorganotin. /Triorganotin compounds/
• Stannane, chlorotrimethyl-: ACTIVE
• Triorganotin compounds have been used experimentally in controlled-release formulations to control the infective snail vector in the debilitating tropical disease schistosomiasis (bilharzia) and to control mosquitoes in stagnant ponds. As yet, the large-scale use of such methods has little support in the host third world countries where these problems are most severe. /Triorganotin compounds/
• In vitro exposure of PHA-stimulated human lymphocytes to organotin compounds resulted in statistically significant increases in the frequencies of hyperdiploid cells. When taken together with our previous study demonstrating spindle inhibiting effects of the same organotin compounds by an indirect method, the present study strongly indicates that organotin compounds are able to induce aneuploidy, probably by affecting spindle function.
