CAS 2905-21-7

2-fluorobenzenesulfonyl chloride

Description:

2-Fluorobenzenesulfonyl chloride, with the CAS number 2905-21-7, is an aromatic sulfonyl chloride characterized by the presence of a fluorine atom attached to the benzene ring. This compound features a sulfonyl chloride functional group (-SO2Cl), which is known for its reactivity, particularly in nucleophilic substitution reactions. The fluorine substituent enhances the electrophilicity of the sulfonyl chloride, making it a useful intermediate in organic synthesis, particularly for the introduction of sulfonyl groups into various organic molecules. It is typically a colorless to pale yellow liquid or solid, depending on the temperature and purity. The compound is sensitive to moisture and should be handled under anhydrous conditions, as it can hydrolyze to form the corresponding sulfonic acid. Safety precautions are essential when working with this substance due to its corrosive nature and potential to release toxic gases upon reaction with water or amines. Overall, 2-fluorobenzenesulfonyl chloride is a valuable reagent in the synthesis of pharmaceuticals and agrochemicals.
