Sodium Hypophosphite Specification

Sodium Hypophosphite (CAS NO.7681-53-0) is also named as HSDB 6032 ; Hypophosphorous acid monosodium salt ; Monosodium hypophosphite ; Natriumhypophosphit ; Natriumhypophosphit [German] ; Phosphinic acid monosodium salt ; Phosphinic acid, sodium salt ; Sodium hydrogen phosphite (NaH₂PO₂) ; Sodium hypophosphite (NaH₂PO₂) ; Sodium phosphinate ; Sodium phosphinate (NaH₂PO₂) . Sodium Hypophosphite (CAS NO.7681-53-0) is odorless white crystals at room temperature. It is soluble in water, and easily absorbs moisture from the air. Sodium hypophosphite should be kept in a cool, dry place, isolated from oxidizing materials. It produces toxic phosphine gas when heated, causing irritation to the respiratory tract.
