Application:	A precursor to hybrid organic-inorganic based molecular batteries with applications as cation-insertion electrodes.
Application:	PAH was used in preparing Mo-Al₂O₃ catalysts in an attempt to produce ultra-low sulphur diesel.
General description:	Phosphomolybdic acid hydrate (PAH) is yellow and crystallisable compound. It precipitates from potash, oxides of rubidium, caesium and thallium, ammonia and other nitrogenous organic alkaloids.
Other Notes:	Review: of the folin phenol method for the quantitative determination of proteins
