Used as a key intermediate in organic synthesis, particularly in the preparation of sulfones and sulfoxides through oxidation or coupling reactions. It serves as a source of the tert-butylsulfinyl anion, enabling the introduction of the tert-butylsulfinyl group in pharmaceutical compounds. Commonly employed in the development of chiral auxiliaries for asymmetric synthesis, especially in the production of bioactive molecules and medicinal agents. Also utilized in radical reactions as a mild reducing agent or scavenger. Its stability and solubility in polar solvents make it suitable for use in various laboratory-scale and industrial chemical processes.
