Description

Compared with other compounds in its class, the molecular weight of 318.30 g/mol gives (3R)-10-(1-AMINOCYCLOPROPYL)-9-FLUORO-2,3-DIHYDRO-3-METHYL-7-OXO-7H-PYRIDO[1,2,3-DE]-1,4-BENZOXAZINE-6-CARBOXYLICACID distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (3R)-10-(1-AMINOCYCLOPROPYL)-9-FLUORO-2,3-DIHYDRO-3-METHYL-7-OXO-7H-PYRIDO[1,2,3-DE]-1,4-BENZOXAZINE-6-CARBOXYLICACID (CAS 166665-94-7), a certified reference material (molecular formula C16H15FN2O4, MW 318.30 g/mol) for analytical method development and quality control.

The molecular framework of (3R)-10-(1-AMINOCYCLOPROPYL)-9-FLUORO-2,3-DIHYDRO-3-METHYL-7-OXO-7H-PYRIDO[1,2,3-DE]-1,4-BENZOXAZINE-6-CARBOXYLICACID (C16H15FN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
