Overview

Phosphomolybdic acid (PMA) hydrate is primarily used in spectrophotometric determination of phosphate ions. PMA is a component in the 3-color histology stain called Masson’s trichrome; employed in the differentiation step, Phosphomolybdic acid is one of the solutions fixed tissues are immersed in prior to subsequent staining. Phosphomolybdic acid is also used as reagent for simple and rapid colorimetric determination of phenothiazine derivatives. PMA oxidizes the phenothiazine derivative to a cationic free radical, forming a coloured salt. A preliminary extraction is necessary if certain reductants (sulphite or ascorbic acid) are present as stabilizers, as they will reduce the reagent to phosphomolybdenum blue.

A reagent used for spectrophotometric determination of phosphate ions.Employed in preparation of a hybrid organic-inorganic, electroactive material with potential application as a cation-insertion electrode in batteries.

Phosphomolybdic acid hydrate may be used in the synthesis of molybdenum disulfide (MoS2)-reduced graphene oxide (RGO) composites with potential application as electrodes for sodium ion battery. It may also be used as a catalyst precursor in the presence of hydrogen peroxide as oxidant for the dibenzothiophenes oxidation in diesel fuels.

A precursor to hybrid organic-inorganic based molecular batteries with applications as cation-insertion electrodes.
