William Blythe’s tin (II) chloride is used in a wide range of applications, where either its reducing nature or role as a source of Sn2+ ions is important. For example, its reducing properties are used in conjunction with catalysts for sensitising nonconductive surfaces prior to electroless metal plating, a technique widely used in the electronics industry. Tin (II) chloride is also used for the manufacture of tin derivatives (e.g. stannous octoate); for formulating into metal plating solutions, as a flux in metal bonding systems and as a cross-linking catalyst.

Tin (II) chloride also plays an important role in the pharmaceutical and fine chemicals industries in reactions where sensitive side chains cannot be affected, for example in key stages in the synthesis of pharmaceutically active heterocyclic nitrogen molecules (indoles and benzimidazoles).

William Blythe’s tin (II) chloride is available as an anhydrous white powder that is used for its properties as a catalyst and reducing agent in applications from pharmaceutical synthesis to construction. It is also available as a clear and colourless solution in customised concentrations to meet your specific requirements. William Blythe also offers an application-specific grade of tin (II) chloride solution for the mirror coating industry.
