Chemical Structure
Description
The molecular framework of 1,3-dibromo-7-methylimidazo[1,5-a]pyridine (C8H6Br2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 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).
1,3-dibromo-7-methylimidazo[1,5-a]pyridine (CAS 1785486-67-0), molecular formula C8H6Br2N2 and molecular weight 289.95 g/mol, is a CATO reference standard with documented purity and traceability.
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.
