Chemical Structure
Description
The molecular framework of 4-Chloro-N,N-diethyl-3-nitrobenzenesulfonamide (C10H13ClN2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 4-Chloro-N,N-diethyl-3-nitrobenzenesulfonamide (CAS 127-53-7), a certified reference material (molecular formula C10H13ClN2O4S, MW 292.74 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.
