The IUPAC name of Diammonium molybdate is diazanium dioxido(dioxo)molybdenum . With the CAS registry number 13106-76-8, it is also named as Ammonium molybdate ((NH₄)₂MoO₄) ; Diammonium tetraoxomolybdate(2-) ; Ammonium molybdate(VI) ; Molybdate (MoO₄^2-), ammonium (1:2), (T-4)- ; Molybdic acid (H₂MoO₄), diammonium salt ; Molybdic acid, diammonium salt .

The product's categories are industrial/fine chemicals, inorganics, ammonium salts chemical synthesis, catalysis and inorganic chemistry, metal and ceramic science. It is white powder which is soluble in water, acid and alkali, and insoluble in alcohol . Diammonium molybdate is used as pigments, color lakes and fabric antiflaming fireproofing agent. It is the main raw material for preparation of molybdenum products and also an important agricultural fertilizer.

The Diammonium molybdate is highly toxic. It will produce toxic molybdenum compounds, nitrogen oxides and ammonia fumes by high temperature. So the storage environment should be ventilate, low-temperature and dry. It is irritating to eyes, respiratory system and skin. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If you want to contact this product, you must wear suitable protective clothing.
