Molybdic acid, commonly provided as a mixture of various hydrated molybdenum oxides, is a critical component in analytical chemistry. This ACS reagent grade material is specifically tested to meet the stringent requirements of the American Chemical Society, ensuring high reliability for quantitative analysis. It is most frequently utilized in the "molybdenum blue" method for the colorimetric determination of phosphates and silicates in water and biological fluids. Furthermore, it serves as a precursor for the synthesis of molybdenum-based catalysts and as a reagent in the production of pigments and ceramic glazes.
Advantages
- Meets or exceeds ACS specifications for analytical reagents, ensuring low levels of interfering impurities.
- High molybdenum content (≥85.0% as MoO₃) for consistent stoichiometric performance.
- Essential reagent for sensitive phosphate and arsenate detection protocols.
- Versatile use in metallographic etching and specialized chemical synthesis.
- Stable powder form for ease of handling and long-term laboratory storage.
