Description:
Phosphorus acid is used as an intermediate in the preparation of other phosphorus compounds like potassium phosphite, ammonium phosphite and calcium phosphite. It is actively involved in the preparation of phosphites like aminotris(methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) and 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), which find application in water treatment as a scale or corrosive inhibitor.Chenodeoxycholic Acid It is also used in chemical reactions as a reducing agent.E1210 Its salt, lead phosphite is used as PVC stabilizer.PMID:23460641 It is also used as precursor in the preparation of phosphine as well as an intermediate in the preparation of other phosphorus compounds.
