Sodium Tungstate Dihydrate

CAS# 10213-10-2

Sodium Tungstate Dihydrate is an inorganic chemical used in many fields for productions in the chemical industry, medical industry, metal and textile industries, glass industry and many others.

Sodium tungstate dihydrate is commercially available in the form of a white crystalline solid or powder. It is usually used in the synthesis of inorganic compounds, (in polyoxometalates synthesis).

Sodium tungstate dihydrate is also used as a catalyst or as a catalyst precursor in several organic reactions (epoxidation, cleavage of double bonds, oxidation of alcohols, amines, imines, organosulfur compounds, halogenation of aromatic compounds, synthesis of β–aryl vinyl bromides and synthesis of 1-H-tetrazoles).
