Product name
Chemical name: Sodium hypophosphite(Sodium Hypophosphite)
Alias: Phosphinicacid,sodiumsalt;phosphinicacidmonosodiumsalt;sodiumhydrogenphosphite(nah2po2);sodiumhydrophosphite;Chemicalbooksodiummonophosphate;sodiumphosphinate;sodiumphosphinate(nah2po2);SodiumhypophosphiteVetec(TM)reagentgrade,98%
Abbreviation: SHPP/HYPO
Physicochemical property
Molecular formula: NaH2PO2·H2O
Molecu No.: 10039-56-2
Appearance: white granular crystal
Sodium hypophosphite is crystalline water with one molecule. Salty, easy to absorb moisture, soluble in water, alcohol, glycerin, insoluble in ether. Heating above 200° C causes sudden decomposition and releases phosphine. Sodium hypophosphite is a strong reducing agent that explodes when exposed to strong oxidants.
