INTRODUCTION
Stannic chloride pentahydrate is a tin source compatible with chlorides. Biologically, it induces a slight inhibition in the catalytic activity of the enzyme horse liver alcohol dehydrogenase (HLADH). The pentahydrate is substitute for its anhydrous grade in applications where presence of water is permissible. Historically, stannous chloride was used as warfare chemical as it forms thick HCl fumes when in contact with water.
Manufacture
Stannic chloride is produced by chlorination of metallic tin by chlorine gas.
