  • Applications

    Applications of Sodium Formaldehyde Bisulfite (CAS 870-72-4) include its use as a formaldehyde-releasing donor and sulfite source in industrial manufacturing; as an intermediate in organic synthesis and as a component in resin, adhesive, and coating formulations; as a stabilizer or controlled-release source of formaldehyde in process liquids; as a mild reducing agent in textile, paper, and leather processing; and as a precursor for specialty organic compounds in chemical production. The exact uses depend on local regulations and formulation limits.
