Sodium benzenesulfinate(CAS: 873-55-2)

Sodium benzenesulfinate is a chemical compound with the CAS number 873-55-2. It has the chemical formula C6H7NaO2S and is commonly used as an intermediate in organic synthesis. This white crystalline solid is soluble in water and has a mild sulfurous odor. It is a precursor for various sulfonate derivatives and is known for its reactivity in chemical reactions involving sulfinate groups.

Sodium benzenesulfinate is widely used in pharmaceuticals for the synthesis of sulfonamide drugs. It also finds applications in industrial processes, such as the production of dyes and pesticides. In research, it serves as a valuable reagent for creating sulfonate compounds. Additionally, it is used in the food industry as a stabilizer and in chemical manufacturing for functional group transformations.

Sodium benzenesulfinate is generally considered safe when handled properly. However, it should be used with caution due to potential irritation to the skin, eyes, and respiratory system. Protective measures such as gloves, goggles, and a fume hood are recommended. Safety standards require proper storage and handling to prevent exposure, and it is classified as a hazardous substance under certain regulations.

Sodium benzenesulfinate should be stored in a cool, dry, and well-ventilated place, away from moisture and direct sunlight. It is best kept in a sealed container at a temperature below 25°C. Due to its hygroscopic nature, it requires careful control of humidity levels. Storage in a chemical storage cabinet is recommended to ensure stability and safety.
