Ammonium molybdate is an odorless crystalline compound ranging in color from white to yellow-green. Ammonium molybdate is an odorless crystalline compound ranging in color from white to yellow-green. Also called molybdic acid hexammonium salt tetrahydrate, ammonium molybdate tetrahydrate and ammonium heptamolybdate tetrahydrate. In chemistry a Ammonium molybdate is a compound containing an oxoanion with molybdenum in its highest oxidation state of 6. Ammonium molybdate can form a very large range of such oxoanions which can be discrete structures or polymeric extended structures, although the latter are only found in the solid state. The discrete Ammonium molybdate oxoanions range in size from the simplest MoO42−, found in potassium molybdate up to extremely large structures found in isopoly-molybdenum blues that contain for example 154 Mo atoms.   Specifications - Ammonium Molybdate  Product-  Ammonium Molybdate  Synonyms-  Molybdic acid hexammonium salt tetrahydrate; ammonium    molybdate tetrahydrate; ammonium heptamolybdate,    tetrahydrate.  CAS NO.-  12027-67-7 (Anhydrous); 12054-85-2 (Tetrahydrate)  Molecular Formula-  [NH4]6Mo7O24.4H2O.  Molecular Weight-  1235.86  Appearance-  white - off white crystalline powder.  Solubility-  soluble in water.  LOD-  1 % max.  Sulphate-  50 ppm max.  Iron-  5 ppm max.  Assay Of Ammonium Molybdate-  99.0 % min - 101.0 % max.
