CAS No.: 6031-21-5
Molecular formula: H3PO2 Molecular Weight: 66.0
Property:The pure form of this product is a colorless crystal with the density of (19°C)1.493 and the melting point of 26.5°C. It can be mixed with water in any proportions. Being a strong reducer, it can be easily oxidized in air. If the anhydrous acid is heated to 130-140°C, it will be decomposed into PH3 and H3PO4 . Technical Index:
