5-Bromo-1,4-dimethyl-1H-1,2,3-triazole (CAS 1040275-55-5) is a high-purity analytical reference standard with the molecular formula C4H6BrN3 and a molecular weight of 176.01 g/mol.
The molecular framework of 5-Bromo-1,4-dimethyl-1H-1,2,3-triazole (C4H6BrN3) is characterized by a nitrile group, bromine 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.
