Description
Compared with other compounds in its class, the molecular weight of 179.61 g/mol gives 4-(4-Chlorophenyl)-4H-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(4-Chlorophenyl)-4H-1,2,4-triazole (CAS 90002-05-4) is a high-purity analytical reference standard with the molecular formula C8H6ClN3 and a molecular weight of 179.61 g/mol.
The molecular framework of 4-(4-Chlorophenyl)-4H-1,2,4-triazole (C8H6ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
