List of organotin compounds
WebTin can combine with other chemicals to form compounds. Combinations with chemicals like chlorine, sulfur, or oxygen are called inorganic tin compounds (i.e., stannous chloride, stannous sulfide, stannic oxide). These are used in toothpaste, perfumes, soaps, food additives and dyes. Tin also can combine with carbon to form organotin compounds WebAPPLICATIONS OF CERTAIN ORGANOTIN COMPOUNDS Final Report - September 2005 prepared for the European Commission by Risk & Policy Analysts Limited (RPA), Farthing Green House, 1 Beccles Road, Loddon, Norfolk, NR14 6LT, UK Tel: +44 1508 528465 Fax: +44 1508 520758 Email ...
