Chemical Structure
Description
The molecular framework of 3-Amino-5-chloro-6-(2H-1,2,3-triazol-2-yl)pyridine (C7H6ClN5) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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).
3-Amino-5-chloro-6-(2H-1,2,3-triazol-2-yl)pyridine (CAS 1832583-43-3) is a high-purity analytical reference standard with the molecular formula C7H6ClN5 and a molecular weight of 195.61 g/mol.
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.
