2-Ethoxybenzenesulfonyl chloride(CAS: 68800-33-9)

2-Ethoxybenzenesulfonyl chloride is a white crystalline solid with a molecular weight of approximately 243.24 g/mol. It is slightly soluble in water but soluble in organic solvents such as dichloromethane and ethanol. Chemically, it is a reactive compound, prone to hydrolysis under basic conditions. It can react with amines to form amides and with nucleophiles to form substituted products.

2-Ethoxybenzenesulfonyl chloride is typically synthesized by reacting p-ethoxybenzenesulfonic acid with thionyl chloride. The reaction is carried out under anhydrous conditions, and the yield is generally high with selectivity towards the desired product. The process requires careful control of temperature and the use of a suitable catalyst to achieve optimal results.

2-Ethoxybenzenesulfonyl chloride is used in various industries, particularly in pharmaceuticals for its role as an intermediate in the synthesis of medicinal compounds. It is also utilized in the production of polymers and as a reagent in organic synthesis for the preparation of other functionalized benzenesulfonates.

When handling 2-Ethoxybenzenesulfonyl chloride, it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and a laboratory coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be cleaned up carefully using appropriate absorbent materials, and the substance should be stored in a cool, dry, and well-ventilated area away from incompatible materials. Always consult the Safety Data Sheet (SDS) for detailed information on handling and disposal.
