Used primarily in research and specialized chemical synthesis, this compound serves as a precursor in the preparation of other tungsten-based materials. It acts as a catalyst or reagent in certain organic transformations and inorganic reactions, particularly those involving metal halide systems. Due to its reactivity with air and moisture, it is handled under controlled conditions, such as inert atmosphere environments. It also finds use in the development of tungsten-containing thin films and advanced materials for electronic and catalytic applications.
