Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(1-(2-Bromophenyl)ethyl)-1H-1,2,3-triazole-4-carboxylic acid (CAS 1707371-76-3), a certified reference material (molecular formula C11H10BrN3O2, MW 296.12 g/mol) for analytical method development and quality control.
The molecular framework of 1-(1-(2-Bromophenyl)ethyl)-1H-1,2,3-triazole-4-carboxylic acid (C11H10BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
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.
