Chemical Structure
Description
The molecular framework of 4-(4-Nitrilophenyl)-1H-1,2,3-triazole-5-carbonitrile (C10H5N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
4-(4-Nitrilophenyl)-1H-1,2,3-triazole-5-carbonitrile (CAS 1119392-20-9), molecular formula C10H5N5 and molecular weight 195.18 g/mol, is a CATO reference standard with documented purity and traceability.
