Phosphinic acid is a phosphorus oxoacid that consists of a single pentavalent phosphorus covalently bound via single bonds to two hydrogens and a hydroxy group and via a double bond to an oxygen.The parent of the class of phosphinic acids. Stability: generates hydrogen phosphide, phosphoric acid, phosphorous acid and hydrogen if contact with strong heat or oxidant. It is a weak acid and forms only one series of salts, the hypophosphites. Phosphinylidene-containing acids react selectively under these conditions, while disubstituted phosphinic acids and phosphonic acids remain unchanged. PE plastic drum, net weight 25kg, 250kg or IBC specification 1000kg. II. Hypophosphorous acid is a phosphorus oxoacid and a powerful reducing agent.Inorganic chemists refer to the free acid by this name (also as "HPA") although its official IUPAC name is phosphinic acid.See Phosphinic acid.It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols.
