  • Applications

    Molybdenum chloride (CAS 11119-46-3) is primarily used as a reagent and precursor in inorganic synthesis and materials processing. In practice, it serves as a precursor for preparing other molybdenum halide complexes and related catalytic systems, acting as a Lewis acid and a chlorinating agent in selected organic and polymerization reactions. It also functions as a source of molybdenum for thin-film and coating technologies and as a building block for catalyst systems in fine chemicals and petrochemicals. In laboratory and pilot-plant settings, it is used to synthesize organomolybdenum compounds and as a reagent in surface-treatment and etching workflows where specialized molybdenum chemistry is needed. Use is subject to appropriate controls and local regulations.
