4-(4-Fluorophenyl)-3,4-dihydrobenzo[4,5]imidazo[1,2-a][1,3,5]triazin-2(1h)-imine (CAS 305852-99-7) is a high-purity analytical reference standard with the molecular formula C15H12FN5 and a molecular weight of 281.29 g/mol.
The molecular framework of 4-(4-Fluorophenyl)-3,4-dihydrobenzo[4,5]imidazo[1,2-a][1,3,5]triazin-2(1h)-imine (C15H12FN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
