4-(2,4-Difluorobenzoyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one CAS 317822-35-8

Description

4-(2,4-Difluorobenzoyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one (CAS 317822-35-8), molecular formula C16H12F2N2O2 and molecular weight 302.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(2,4-Difluorobenzoyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-(2,4-Difluorobenzoyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one 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.
