Description

As a certified reference material (CRM), 8-bromo-7-fluoro-2-methoxy-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

8-bromo-7-fluoro-2-methoxy-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline (CAS 1706965-72-1), molecular formula C12H14BrFN2O and molecular weight 301.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-bromo-7-fluoro-2-methoxy-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxaline (C12H14BrFN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
