Used as a source of molybdenum in agricultural fertilizers to correct micronutrient deficiencies in crops, especially in legumes and citrus plants. Plays a role in enzyme systems that help nitrogen fixation and nitrate reduction in plants.

Applied in industrial water treatment to prevent corrosion in cooling systems, boilers, and heat exchangers due to its passivating properties that form a protective film on metal surfaces.

Serves as an additive in lubricants and greases to enhance anti-wear and anti-corrosion properties.

Serves as a catalyst or catalyst precursor in petroleum refining and chemical synthesis processes.

Utilized in analytical chemistry for the detection and determination of phosphates and silicates through colorimetric methods, such as in water samples.

Employed in the production of molybdenum-based pigments, ceramics, and glass to control color and improve corrosion resistance.

Also used as a precursor for other molybdenum compounds in various industrial applications.
