(7,8-Dimethyl-2-oxo-2H-chromen-4-yl)methyl (2-fluorobenzoyl)glycinate (CAS 868269-33-4), molecular formula C21H18FNO5 and molecular weight 383.37 g/mol, is a CATO reference standard with documented purity and traceability.
(7,8-Dimethyl-2-oxo-2H-chromen-4-yl)methyl (2-fluorobenzoyl)glycinate (C21H18FNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 (7,8-Dimethyl-2-oxo-2H-chromen-4-yl)methyl (2-fluorobenzoyl)glycinate 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.
