The CAS number of Ammonium Molybdate [(NH₄)₆Mo₇O₂₄·4H₂O] is 12054-85-2. The molecular weight is 1235.86 g/mol. Meghachem's standard specification is MoO3 at 81.00% minimum and Mo at 54.50% minimum. A Certificate of Analysis confirming all five quality parameters is provided with every shipment.

Ammonium Molybdate is used across four main industrial applications. First, as a catalyst in Copper Phthalocyanine crude synthesis for pigment production. Second, as a primary source of molybdate ions and an analytical reagent for phosphate and silicate detection in laboratories. Third, as a process catalyst in coal technology for dehydration and desulfurization. Fourth, and perhaps most important volumetrically, as a raw material for the production of molybdenum trioxide and high-purity molybdenum metal powder used in steel alloys, aerospace components, and electronics.

Ammonium Molybdate [(NH₄)₆Mo₇O₂₄·4H₂O] contains ammonium as the counter-ion and is preferred for applications where ammonia-based chemistry is process-compatible, such as catalyst preparation, analytical reagent work, and molybdenum metal production where the ammonium can be driven off during calcination without leaving problematic residues. Sodium Molybdate [Na₂MoO₄·2H₂O] contains sodium and is more commonly used as a corrosion inhibitor in cooling water systems, as a micronutrient fertilizer additive, and in processes where sodium is tolerated. The key decision factor is whether sodium or ammonium ions are acceptable in the final process or product.

Our standard specification covers five parameters: MoO3 at 81.00% minimum, Mo at 54.50% minimum, Chloride at 0.05% maximum, Insoluble matter at 0.01% maximum, and Iron at 0.01% maximum. The product is 100% soluble in aqueous ammonia solution. A Certificate of Analysis is provided with every shipment. Custom purity grades can be discussed for qualifying buyers with specific application requirements.
