Chemical Structure
Description
The molecular framework of 5,7-dibromo-[1,2,4]triazolo[1,5-a]pyridine (C6H11Br2N3) 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.
5,7-dibromo-[1,2,4]triazolo[1,5-a]pyridine (CAS 2306270-61-9) is a high-purity analytical reference standard with the molecular formula C6H11Br2N3 and a molecular weight of 284.98 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
