Acute toxicity LD50: 1895mg / kg (rat oral); 1700mg / kg (mouse oral)

Application of Phosphorous acid:

Monopotassium phosphite is an inorganic compound with the formula KH2PO3. A compositionally related compound has the formula H3PO3.2(KH2PO3). Both are white solids that contain salts of the phosphite anion H2PO3−, the conjugate base of phosphorous acid. These materials have been used in some fertilizers

Storage:

Stored in a cool, ventilated warehouse. Keep away from fire and heat. Packaging requirements sealed, not in contact with air. Should be stored separately with the base, avoid mixing reservoir. The storage area shall be provided with suitable material to contain the spill.
