Phosphorous acid, with the chemical formula H3PO3, is a compound containing phosphorus in the +3 oxidation state. It is a colorless, crystalline solid that is soluble in water and acts as a dibasic acid, capable of donating two protons per molecule. Phosphorous acid is primarily used as a fungicide in agriculture, helping to control fungal diseases in crops like citrus fruits, grapes, and vegetables. Additionally, it serves as a key chemical intermediate in the synthesis of various phosphorus-containing compounds used in flame retardants, plasticizers, and pharmaceuticals. In water treatment, phosphorous acid is sometimes employed to inhibit algae growth. Furthermore, it finds application as a laboratory reagent for chemical reactions, especially in the production of phosphonates and phosphonic acids.
