Answer:It is at ≥99.99% on a trace-metals basis, with total metallic impurities below 100 ppm.
Answer:It is used in heteropolyacid chemistry, preparation of polyoxometalate materials and catalysts, and selected staining formulations.
Answer:No. It is supplied as crystalline phosphomolybdic acid hydrate and must be prepared for the intended protocol.
Phosphomolybdic acid hydrate is a crystalline heteropolyacid used as an oxidizing reagent and as a building block in inorganic and hybrid-material synthesis. This high-purity grade is at at least 99.99% on a trace-metals basis, with total metallic impurities below 100 ppm. The 10 g package is appropriate for research requiring tight control of trace metal contamination in reagent inputs. Phosphomolybdic acid hydrate has the composition H3[P(Mo3O10)4]·xH2O and CAS number 51429-74-4. It supports preparation of polyoxometalate-based materials, molybdenum-containing catalyst systems, and related advanced materials. It is also a component of Goldner's trichrome staining formulations. The crystalline form and high-purity designation distinguish this material from lower-grade phosphomolybdic acid reagents and from ready-made staining solutions. Solubility, reagent concentration, and oxidation conditions should be established for the target reaction or preparation. The specification includes a maximum of 0.01% insoluble matter alongside limits for selected anion and cation impurities.
