7-Amino-6-bromo-1,8-naphthyridine-3-carbonitrile (CAS 2691878-61-0), molecular formula C9H5BrN4 and molecular weight 249.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Amino-6-bromo-1,8-naphthyridine-3-carbonitrile (C9H5BrN4) 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).
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.
