Sodium benzenesulfinate

　　Main Uses

　　Organic synthesis intermediate: Used for the preparation of benzenesulfonyl chloride, aromatic sulfones, etc., and is an important raw material for the synthesis of dyes, pharmaceuticals, and pesticides. For example, by reacting with haloalkanes to form sulfone compounds, which can serve as active groups in drug synthesis.

　　Antioxidant: Due to its certain reducing properties, it can be used as an antioxidant in some reaction systems to prevent raw materials or products from being oxidized.

　　Electroplating additive: In the electroplating industry, it can be used as a brightener or auxiliary agent to improve the uniformity and gloss of the coating.

　　Pharmaceutical field: Used as an intermediate for the synthesis of antibacterial and anti-inflammatory drugs, etc.; its derivatives can modulate efficacy and stability in drug molecular design.
