Description and Uses
Sodium Hydroxymethanesulfinate Hydrate is the hydrated version of Sodium Hydroxymethanesulfinate (S634950), which 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 (e.g. p-Anisidine [A673505]) to synthesize anilinomethanesulfonates.
