Phosphorous Acid is primarily used as a chemical intermediate in the production of various phosphorus compounds, particularly as a key component in the manufacturing of PVC stabilizers like basic lead phosphite, and also serves as a strong reducing agent in organic synthesis; its applications include the production of synthetic fibers, organophosphorus pesticides, and highly efficient water treatment agents like ATMP (aminotrimethylene phosphonic acid).
