4-((6-Fluoro-2,3-dihydro-2-methyl-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzonitrile (CAS 1159978-64-9), molecular formula C17H13FN2O2 and molecular weight 296.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((6-Fluoro-2,3-dihydro-2-methyl-3-oxobenzo[b][1,4]oxazin-4-yl)methyl)benzonitrile (C17H13FN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
