Hydroxymethanesulfinic acid is an organic acid. Sodium salt of hydroxymethanesulfinic acid (rongalite) is widely used in organic synthesis. It can be used as a reducing agent for elemental selenium and tellurium, diselenides, α‐halo ketones, and aromatic aldehydes; yields symmetrical sulfones with primary halides and with Michael acceptors.
