Sodium Stannate Trihydrate Product Identification CAS NO. 12058-66-1 (Anhydrous) 12209-98-2 (Trihydrate) 12027-70-2 (Hexahydroxide) EINECS NO. 235-030-5 (Trihydrate) 234-724-5 (Hexahydroxide) FORMULA Na2SnO3·3H2O or Na2Sn(OH)6 MOL WT. 266.71 SYNONYMS Disodium Tin Trioxide; Disodium tin hexahydroxide; Physical And Chemical Properties PHYSICAL STATE white to off-white powder NFPA RATINGS Health: 1 Flammability: 0 Reactivity: 0 STABILITY Stable under ordinary conditions Tributyltin compounds are usually clear to yellowish liquids with an unpleasant odor. Triphenyltincompounds are white solids with low vapour pressures. Tri-organotin compounds are derivatives of tetravalent tin. They are lipophilic and have low water solubility. Physical and chemical properties of tri-organotin compounds vary depending upon the anion linked to tin. Tributyltin derivatives have toxic properties to gram positive bacteria are used as disinfectants on surfaces such as hospital floors and sports arenas, combined with gram negative bactericides. Tin chemicals also used as flame retardants to treat fabrics and plastics. Tributyltin methacrylate is used as a stabiliser for PVC. Other industrial applications of organotin compounds include as rodent repellents, antioxidants, curing agents and corrosion inhibitors. Sodium stannate is used as a salt in alkaline tin plating electrolyte. It is used in surface coatings (paper). It is used in manufacturing other metallic stannates and tin oxide coatings.
