Specifications
It is the main stuff be used to manufacture the herbicide---glyphosate and also be used to manufacture phosphite etc.
Phosphorous acid is used in chemical reactions as a reducing agent that is somewhat less vigorous than the related hypophosphorous acid
Pure product is white crystals, specific gravity 1.651(21.2°C). M.P. 73.6°C, B.P. 200°C. Soluble in water and ethanol easily, and it will be oxidized into H3PO4 in the air slowly. Be decomposed into H3PO4 and phosphine when be heated to the temperature 180°C.H3PO3 is a kind of diacid, its acid-stage is higher than H3PO4. Be oxidized easily and has strong hygroscopy and corrosivity.
