Used as a precursor in the production of molybdenum-based catalysts for petroleum refining, especially in hydrodesulfurization processes. It is also employed in corrosion inhibitors for metals, providing protection against oxidation and environmental degradation. In agriculture, it serves as a source of molybdenum in fertilizers to support nitrogen fixation in leguminous plants. Additionally, it finds use in electroplating baths to improve wear resistance and in the manufacture of pigments and flame retardants for plastics and coatings.
