Ammonium molybdate is a colorless, white, or slightly greenish-yellow powder. It is commonly used in chemical analysis to determine phosphorus content. When dissolved in nitric acid, it precipitates phosphorus as ammonium phosphomolybdate, with the formula (NH4)3PO4·12MoO3, after being dried at 110°C (230°F).

This compound plays a crucial role in the evaluation and separation of alkali metals and is also used as a reagent for detecting alkaloids. Additionally, ammonium molybdate is employed in various industrial and laboratory applications, making it an essential chemical in both analytical and synthetic processes.
