What is Ammonium molybdate?
Ammonium molybdate (CAS 13106-76-8), also known as diammonium molybdate, is an inorganic molybdenum salt; a source of soluble molybdenum.
Where is Ammonium molybdate used?
- Agriculture: micronutrient in liquid fertilizers and foliar sprays
- Crop nutrition: corrects molybdenum deficiency in legumes and brassicas where nitrogen fixation depends on molybdenum availability
- Water treatment: corrosion inhibitor forming a protective film on metal surfaces in cooling water systems
- Analytical chemistry: active reagent in phosphate and silicate detection methods
- Catalyst precursor for hydroprocessing and chemical synthesis
Commercial specifications
- Purity levels range from technical grade to reagent grade
- Bulk supply for fertilizer and industrial buyers; smaller packaging for analytical and pharmaceutical procurement
