Used as a precursor in the production of molybdenum-containing catalysts for petroleum refining, especially in hydrodesulfurization processes. Commonly applied in the synthesis of thin-film coatings and electronic materials through chemical vapor deposition (CVD) or spin-coating techniques. Employed in metallurgy for alloying steel and superalloys to enhance strength, hardness, and corrosion resistance. Also utilized in the preparation of molybdenum-based nanomaterials and in analytical chemistry as a reagent for detecting certain compounds like phosphates in water samples.
