Phosphomolybdic acid hydrate is an ACS-grade heteropoly acid used as an electron-dense metal stain and laboratory reagent. It is also known as 12-molybdophosphoric acid or molybdophosphoric acid.
In staining workflows, phosphomolybdic acid may contribute contrast through its molybdenum-containing structure. Its performance depends on reagent concentration, specimen preparation, staining time, and the complete laboratory procedure.
It is intended for laboratory applications requiring ACS-grade phosphomolybdic acid hydrate. Follow a validated protocol and confirm compatibility with the selected specimen, reagents, and imaging method.
