Chemical Structure

6-Bromo-3-phenyl-2H-chromen-2-one CAS 16807-67-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 301.13 g/mol gives 6-Bromo-3-phenyl-2H-chromen-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Bromo-3-phenyl-2H-chromen-2-one (CAS 16807-67-3), molecular formula C15H9BrO2 and molecular weight 301.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Bromo-3-phenyl-2H-chromen-2-one (C15H9BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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.

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.
