Ammonium Molybdate USP
(NH4)6Mo7O24-4H2O 1235.86
Molybdate (Mo7O24 6 ), hexaammonium, tetrahydrate.
Hexaammonium molybdate tetrahydrate [12054-85-2].
Ammonium Molybdate contains not less than 99.3 percent and not more than 101.8 percent of (NH4)6Mo7O244H2O.

Identification: Dissolve 0.6 g of it in 1.4 mL of water and 1.45 mL of ammonium hydroxide. Cool this mixture, and add slowly, with mixing, 7.2 mL of a well-cooled mixture of 3.2 mL of nitric acid and 4 mL of water. Allow to stand for 24 to 48 hours, and filter through a sintered-glass filter. To 5 mL of the filtrate add 2 mL of dibasic sodium phosphate TS: a yellow precipitate is formed, and it is soluble in an excess of 6 N ammonium hydroxide.
Insoluble substances: Dissolve 20 g in 200 mL of water in a beaker, heat to boiling, cover, and heat on a steam bath for 1 hour. Filter the hot solution through a tared filtering crucible, wash the insoluble residue with hot water, and dry at 105 for 2 hours: the weight of the residue so obtained does not exceed 1 mg (0.005%).
Chloride: Maximum 0.002%.
Limit of nitrate: To pass the test.
Sulfate: Maximum 0.02%.
Arsenate, phosphate, and silicate: To pass the test.
Phosphate: Maximum 5 ppm.
Magnesium and alkali salts: Maximum 0.02%.
Heavy metals: The limit is 10 µg per g.
