This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
Phosphotungstic acid is used as a catalyst for the hydrolysis of propene to prepare 2-propanol. It is also involved in heterogeneous catalysis reaction to prepare propene from 2-propanol and methanol from hydrocarbons. Its ethanolic solution is used in biology as well as to precipitate proteins. It is utilized to precipitate different types of dye such as basic dyes and triphenylmethane dyes. In histology, it is used for staining of cell specimens. It is used in the gravimetric analysis of potassium in analytical chemistry.
Solubility
Soluble in water, alcohol and ether.
Notes
Incompatible with strong bases, strong oxidizing agents.
