Chemical Structure
Description
The molecular framework of 1-(5-Bromo-4H-1,2,4-triazol-3-yl)ethanol (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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-(5-Bromo-4H-1,2,4-triazol-3-yl)ethanol (CAS 2707680-30-4) is a high-purity analytical reference standard with the molecular formula C4H6BrN3O and a molecular weight of 192.01 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
