CATO supplies 4-Benzoyl-1-[(3-fluorophenyl)methyl]-3-methyl-1,2,3,4-tetrahydroquinoxalin-2-one (CAS 317822-20-1), a certified reference material (molecular formula C23H19FN2O2, MW 374.41 g/mol) for analytical method development and quality control.
4-Benzoyl-1-[(3-fluorophenyl)methyl]-3-methyl-1,2,3,4-tetrahydroquinoxalin-2-one (C23H19FN2O2) contains a steroid core, an amide 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. 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-Benzoyl-1-[(3-fluorophenyl)methyl]-3-methyl-1,2,3,4-tetrahydroquinoxalin-2-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.
