Rongalite is a chemical compound with the molecular formula Na⁺HOCH₂SO₂⁻. This salt has many additional names, including Rongalit, sodium hydroxymethylsulfinate, sodium formaldehyde sulfoxylate, and Bruggolite.  It is water-soluble and generally sold as the dihydrate. The compound and its derivatives are widely used in the dye industry.

Applications:

1. Used as industrial bleaching agent and as a reducing agent for vat dyeing.
2. Another large-scale use is as a reducing agent in redox-initiator systems for emulsion polymerization.
3. A niche use is its use as water conditioner for aquaria as it rapidly reduces chlorine and chloramine and reacts with ammonia to form the innocuous aminomethylsulfinate ion.
4. It is also used as an antioxidant in pharmaceutical formulation.
5. The compound has been used increasingly in commercial cosmetic hair dye color removers despite the generation of formaldehyde, a known human carcinogen.
