Description

Compared with other compounds in its class, the molecular weight of 273.51 g/mol gives 7-Bromo-4-chloro-5-methoxycinnoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Bromo-4-chloro-5-methoxycinnoline (CAS 2759952-41-3) is a high-purity analytical reference standard with the molecular formula C9H6BrClN2O and a molecular weight of 273.51 g/mol.

The molecular framework of 7-Bromo-4-chloro-5-methoxycinnoline (C9H6BrClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
