P-TOLUENESULFINIC ACID SODIUM SALT TETRAHYDRATE(CAS: 868858-48-4)

P-Toluenesulfinic acid sodium salt tetrahydrate is a crystalline compound with a molecular weight of approximately 254.28 g/mol. It has a solubility of about 9 g/L in water and exhibits acidic properties. The compound is stable under normal conditions but reacts with bases to form sodium salts. It is highly soluble in polar solvents and slightly soluble in water, making it useful in various chemical applications.

P-Toluenesulfinic acid sodium salt tetrahydrate is synthesized by reacting sodium sulfite with p-toluenesulfonyl chloride in an aqueous medium. The reaction proceeds under mild conditions, and the product crystallizes as a tetrahydrate form. Commonly used catalysts include sodium hydroxide, and the process yields a pure product with high selectivity and good yield.

P-Toluenesulfinic acid sodium salt tetrahydrate finds applications in pharmaceuticals for the synthesis of certain drugs, in polymers for enhancing their properties, and in sensors for detecting various analytes. It is also used in the semiconductor industry for etching and cleaning processes due to its reactivity and stability.

When handling P-toluenesulfinic acid sodium salt tetrahydrate, it is important to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Operations should be conducted in a well-ventilated area or a fume hood to avoid inhalation of fumes. Spills should be cleaned up using appropriate absorbents, and the area should be flushed with water. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
