Cas no 13918-92-8 (2,4-Difluorobenzenesulfonyl chloride)
2,4-Difluorobenzenesulfonyl chloride is a fluorinated aromatic sulfonyl chloride derivative widely used as a key intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. Its highly reactive sulfonyl chloride group enables efficient incorporation into target molecules, while the difluoro substitution enhances electronic and steric properties, improving selectivity in reactions. This compound is valued for its stability under standard conditions and compatibility with various coupling and substitution reactions. It serves as a versatile building block for sulfonamides, sulfonate esters, and other functionalized derivatives. Proper handling is required due to its moisture sensitivity and potential reactivity with nucleophiles.
