2,4-Dichlorophenyl benzenesulfonate(CAS: 97-16-5)

2,4-Dichlorophenyl benzenesulfonate is a crystalline solid with a molecular weight of approximately 269.04 g/mol. It has low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but may react with strong bases. This compound is commonly used in analytical chemistry due to its reactivity and stability under certain conditions.

2,4-Dichlorophenyl benzenesulfonate is typically synthesized through the sulfonation of 2,4-dichlorobenzoic acid with sulfur trioxide (SO3) in the presence of a solvent like methanol. The reaction is exothermic, and careful control of temperature is necessary to achieve high yield and selectivity. Catalysts such as pyridine may be used to enhance the reaction efficiency.

2,4-Dichlorophenyl benzenesulfonate is primarily used in the pharmaceutical industry as an intermediate for the synthesis of certain drugs. It is also employed in the production of dyes, pigments, and other chemical intermediates. Additionally, it finds use in the synthesis of various chemicals and in analytical chemistry due to its reactivity and stability.

Proper personal protective equipment (PPE) should be worn when handling 2,4-dichlorophenyl benzenesulfonate, including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be handled with caution, and appropriate spill kits should be available. Always refer to the Safety Data Sheet (SDS) for detailed information on handling and storage procedures.
