Chemical Structure
Description
The occurrence of 2-(4h-1,2,4-Triazol-4-yl)acetonitrile is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4h-1,2,4-Triazol-4-yl)acetonitrile (CAS 1204193-90-7) is a high-purity analytical reference standard with the molecular formula C4H4N4 and a molecular weight of 108.10 g/mol.
The molecular framework of 2-(4h-1,2,4-Triazol-4-yl)acetonitrile (C4H4N4) is characterized by 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).
