Chemical Structure
Description
The molecular framework of 4-((2,3-Dihydro-2-methyl-6-nitro-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzoic Acid (C17H14N2O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-((2,3-Dihydro-2-methyl-6-nitro-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzoic Acid (CAS 1082303-12-5), molecular formula C17H14N2O6 and molecular weight 342.30 g/mol, is a CATO reference standard with documented purity and traceability.
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-((2,3-Dihydro-2-methyl-6-nitro-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzoic Acid 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.
