5-(3-bromophenyl)-1H-1,2,4-triazole-3-carbonitrile (CAS 328281-85-2) is a high-purity analytical reference standard with the molecular formula C9H5BrN4 and a molecular weight of 249.07 g/mol.
5-(3-bromophenyl)-1H-1,2,4-triazole-3-carbonitrile (C9H5BrN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
