Examples
An example of a simple, well-studied sulfinic acid is phenylsulfinic acid. A commercially important sulfinic acid is thiourea dioxide, which is prepared by the oxidation of thiourea with hydrogen peroxide.
- (NH2)2CS + 2H2O2 → (NH)(NH2)CSO2H + 2H2O
Another commercially important sulfinic acid is hydroxymethyl derivative, which is usually employed as its sodium salt (HOCH2SO2Na). Called Rongalite, this anion is a commercially useful reducing agent.
