3-(3-Chlorobenzenesulfonyl)-6,7-difluoro-1,4-dihydroquinolin-4-one CAS 1325304-64-0

Description

CATO supplies 3-(3-Chlorobenzenesulfonyl)-6,7-difluoro-1,4-dihydroquinolin-4-one (CAS 1325304-64-0), a certified reference material (molecular formula C15H8ClF2NO3S, MW 355.74 g/mol) for analytical method development and quality control.

The molecular framework of 3-(3-Chlorobenzenesulfonyl)-6,7-difluoro-1,4-dihydroquinolin-4-one (C15H8ClF2NO3S) 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 its high hydrophobicity (logP), 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
