2-Nitro-4-(trifluoromethyl)benzenesulfonyl chloride(CAS: 837-95-6)

2-Nitro-4-(trifluoromethyl)benzenesulfonyl chloride is a white crystalline solid with a molecular weight of approximately 356.02 g/mol. It is poorly soluble in water but soluble in organic solvents like dichloromethane and acetonitrile. Chemically, it is highly reactive due to the presence of the nitro and trifluoromethyl groups, which enhance its reactivity in substitution reactions.

2-Nitro-4-(trifluoromethyl)benzenesulfonyl chloride can be synthesized by first sulfonating 4-(trifluoromethyl)benzenesulfonic acid with thionyl chloride, followed by nitration using a mixture of nitric acid and sulfuric acid. This process requires careful control of reaction conditions to achieve high yield and selectivity.

2-Nitro-4-(trifluoromethyl)benzenesulfonyl chloride is used in the pharmaceutical industry for the synthesis of certain intermediates and APIs. It is also utilized in the polymer industry for the preparation of advanced materials. Additionally, it has applications in sensor technologies and semiconductor manufacturing due to its unique chemical properties.

When handling 2-Nitro-4-(trifluoromethyl)benzenesulfonyl chloride, it is crucial to use appropriate personal protective equipment (PPE) including gloves, goggles, and a laboratory coat. Work should be conducted in a fume hood to minimize exposure. Spills should be cleaned up immediately using appropriate absorbents. Always refer to the Safety Data Sheet (SDS) for detailed guidelines on handling and disposal.
