Aplicaciones

It is used as a catalyst in organic synthesis, and as an analytical reagent in laboratories. It is employed in the preparation of vanadate. It acts as a sensor for the determination of N-acetyltransferase activity in humans. Further it finds use in dyes, varnishes, indelible inks, drier for paints, and in photography. With copper carbonate, it has been shown to enhance the catalytic activities. Ammonium metavanadate is an environmental-friendly catalyst to prepare alpha-hydroxyphosphonate derivatives in high yield through the reaction of aryl/heteroaryl aldehydes with triethylphosphonate derivatives.

Notas

It is hygroscopic in nature. It is incompatible with strong oxidizing agents and strong acids.
