8-Quinolinesulfonyl chloride(CAS: 18704-37-5)

8-Quinolinesulfonyl chloride (CAS: 18704-37-5) is a white crystalline solid with a molecular weight of approximately 236.04 g/mol. It has low solubility in water but is more soluble in organic solvents like methanol and ethanol. Chemically, it is highly reactive and susceptible to hydrolysis in the presence of moisture. It is used as a precursor in the synthesis of various pharmaceutical and chemical intermediates.

8-Quinolinesulfonyl chloride is typically synthesized by reacting 8-quinolinesulfonic acid with thionyl chloride. The reaction proceeds under anhydrous conditions to avoid hydrolysis, providing a high yield of the desired product with good selectivity. The process can be optimized with the use of a phase transfer catalyst to improve product purity and yield.

8-Quinolinesulfonyl chloride (CAS: 18704-37-5) is primarily used in the pharmaceutical industry as a precursor for the synthesis of certain active pharmaceutical ingredients. It is also utilized in the polymer industry for the modification of polymer properties, and in the electronic industry for the production of sensors and semiconductors.

When handling 8-Quinolinesulfonyl chloride (CAS: 18704-37-5), it is important to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and lab coats. This compound should be stored in a cool, dry place and handled within a well-ventilated fume hood to avoid contact with moisture. In case of spillage, it should be cleaned up immediately using appropriate absorbent materials and reported to a safety officer. Refer to the Material Safety Data Sheet (MSDS) for detailed instructions and safety precautions.
