2. Basic information of monopotassium phosphite

The monopotassium phosphite (Cas No. 13977-65-6) is one kind of white powder. With its IUPAC name of potassium phosphorous acid, this chemical has its molecular formula of KH2PO3 and molecular weight of 120.07776. When comes to the monopotassium phosphite solubility, it is soluble in water and easily deliquesces in air. Besides, this chemical belongs to the classification code of TSCA Flag P [A commenced PMN (Premanufacture Notice) substance]. 

When comes to the production of monopotassium phosphite, there is one simple method: Prepare the raw material of a potassium ion (e.g. from potassium hydroxide) and phosphorous acid with an equimolar amount, then let them react in some certain circumstances, and finally you could get the final product Monopotassium phosphite. As to its storage, it should be kept sealed in the cool, dry and well-ventilated place, away from heat, direct light.
