Chemical Structure
Description
The molecular framework of 2-(3-Bromo-1H-1,2,4-triazol-1-yl)ethan-1-ol (C4H6BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 2-(3-Bromo-1H-1,2,4-triazol-1-yl)ethan-1-ol (CAS 1630763-72-2), a certified reference material (molecular formula C4H6BrN3O, MW 192.01 g/mol) for analytical method development and quality control.
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.
