N-(3-Chloro-2-quinoxalinyl)-4-fluorobenzenesulfonamide CAS 488744-02-1

Description

N-(3-Chloro-2-quinoxalinyl)-4-fluorobenzenesulfonamide (C14H9ClFN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).

CATO supplies N-(3-Chloro-2-quinoxalinyl)-4-fluorobenzenesulfonamide (CAS 488744-02-1), a certified reference material (molecular formula C14H9ClFN3O2S, MW 337.76 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
