Chemical Structure
Description
N-[4-(4-Fluorobenzenesulfonyl)phenyl]acetamide (CAS 734-22-5) is a high-purity analytical reference standard with the molecular formula C14H12FNO3S and a molecular weight of 293.31 g/mol.
N-[4-(4-Fluorobenzenesulfonyl)phenyl]acetamide (C14H12FNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), N-[4-(4-Fluorobenzenesulfonyl)phenyl]acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
