Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs requiring sulfinate functional groups for their activity. It serves as a key building block in organic reactions, especially in cross-coupling processes where sulfinate salts act as aryl radical precursors. Commonly applied in the preparation of biologically active molecules, including potential antiviral and anti-inflammatory agents. Its stability and reactivity profile make it suitable for use in controlled laboratory-scale reactions aimed at constructing complex aromatic structures.
