Chemical Structure

(R)-9-bromo-8-chloro-10-fluoro-1,2,3,4,12,12a-hexahydro-6H-benzo[f]pyrazino[2,1-c][1,4]oxazepine CAS 2487481-03-6 chemical structure

Description

CATO supplies (R)-9-bromo-8-chloro-10-fluoro-1,2,3,4,12,12a-hexahydro-6H-benzo[f]pyrazino[2,1-c][1,4]oxazepine (CAS 2487481-03-6), a certified reference material (molecular formula C12H13BrClFN2O, MW 335.60 g/mol) for analytical method development and quality control.

Structurally, (R)-9-bromo-8-chloro-10-fluoro-1,2,3,4,12,12a-hexahydro-6H-benzo[f]pyrazino[2,1-c][1,4]oxazepine (C12H13BrClFN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 335.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.
