Description
CATO manufactures 4-(2,6-Difluorobenzoyl)-1-(4-fluorobenzyl)-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.
4-(2,6-Difluorobenzoyl)-1-(4-fluorobenzyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one (CAS 317833-47-9) is a high-purity analytical reference standard with the molecular formula C23H17F3N2O2 and a molecular weight of 410.39 g/mol.
4-(2,6-Difluorobenzoyl)-1-(4-fluorobenzyl)-3-methyl-3,4-dihydroquinoxalin-2(1H)-one (C23H17F3N2O2) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
