Hazards Summary
Produced as a mixture with monomethyltin trichloride (CAS# 993-16-8); Teratogenicity observed in rats administered 20 mg/kg on days 7-17 of gestation; [Shepard's Catalog of Teratogenic Agents] Corrosive to rabbit skin; The nervous system is the target of toxicity in 90-day oral studies of rats, with neuropathological lesions observed in one study at doses as low as 25 ppm (1.6/2.2 mg/kg/day); One oral study of rats produced serious teratogenic effects not considered as related to maternal toxicity; Another study of rats demonstrated no teratogenicity; Possible developmental neurotoxicity observed in other studies of rats; [ECHA - Proposal for Harmonised Classification and Labelling] Reacts with water; Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; Toxic by ingestion, inhalation, and skin absorption; [Alfa Aesar MSDS] See Trimethyltin chloride and Di-n-butyltin dichloride.

Chemie und Industrie
Pharmakologische Informationen
Metabolism/Metabolites
Though tin metal is very poorly absorbed, tin compounds may be absorbed via oral, inhalation, or dermal routes, with organotin compounds being much more readily absorbed than inorganic tin compounds. Tin may enter the bloodstream and bind to hemoglobin, where it is distributed and accumulates mainly in the kidney, liver, lung, and bone. Organotin compounds may undergo dealkylation, hydroxylation, dearylation, and oxidation catalyzed by cytochrome P-450 enzymes in the liver. The alkyl products of dealkylation are conjugated with glutathione and further metabolized to mercapturic acid derivatives. Tin and its metabolites are excreted mainly in the urine and feces. (L308)
