Chemical Structure
Description
4-Acetamido-3-fluorobenzenesulfonyl chloride (CAS 349-71-3) is a high-purity analytical reference standard with the molecular formula C8H7ClFNO3S and a molecular weight of 251.66 g/mol.
The molecular framework of 4-Acetamido-3-fluorobenzenesulfonyl chloride (C8H7ClFNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Acetamido-3-fluorobenzenesulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
