SYNTHESIS AND REACTIONS:

Although available commercially, the salt can be prepared from sodium dithionite and formaldehyde:

Na2S2O4 + 2 CH2O + H2O → HO-CH2-SO3Na + HO-CH2-SO2Na

This reaction proceeds quantitatively, such that dithionite can be determined by its conversion to Rongalite, which is far less O2-sensitive and thus easier to handle.
The hydroxymethanesulfinate ion is unstable in solution towards decomposition to formaldehyde and sulfite.
Addition of at least one equivalent of formaldehyde pushes the equilibrium towards the side of the adduct and reacts further to give the bis-(hydroxymethyl)sulfone.
Such solutions are shelf-stable indefinitely.

Sodium hydroxymethanesulfinate was originally developed in the early 20th century for the textile industry as a shelf-stable source of sulfoxylate ion, where the latter can be generated at will. In use, when sodium hydroxymethanesulfinate is made acidic, the reducing sulfoxylate ion and formaldehyde are released in equimolar amounts. For safety reasons the generation of formaldehyde must be taken into consideration when used industrially.

Sodium hydroxymethanesulfinate can essentially be considered to be a source of SO22−.
As such Sodium hydroxymethanesulfinate is used both as a reducing agent and as a reagent to introduce SO2 groups into organic molecules.
Treatment of elemental Se and Te with NaHOCH2SO2 gives solutions containing the corresponding Na2Sex and Na2Tex, where x is approximately 2.
As a nucleophile, NaHOCH2SO2 reacts with alkylating agents to give sulfones.

HO-CH2-SO2Na + 2 C6H5CH2Br → [C6H5CH2]2SO2 + NaBr + CH2O + HBr

Occasionally, alkylation will occur also at oxygen, thus xylylene dibromide gives both the sulfone and the isomeric sulfinate ester.

MECHANISM OF ACTION:

The mechanism of action of Sodium hydroxymethanesulfinate is not fully understood.
Sodium hydroxymethanesulfinate is believed that the compound acts as a reducing agent, which means it can reduce the oxidation state of other molecules.
Sodium hydroxymethanesulfinate is also believed that Sodium hydroxymethanesulfinate can act as a catalyst in some chemical reactions, as it can increase the rate of reaction by providing an alternative pathway for the reaction to occur.

APPLICATION:

Sodium Hydroxymethanesulfinate is an organic reductant that is stable in alkaline enviroments but readily decomposes in acidic medium to produce a number of products, one of them being sulfur dioxide.
Sodium hydroxymethanesulfinate is also used in conjunction with substituted anilines to synthesize anilinomethanesulfonates.
