Ethyl 2-(3-bromo-1H-1,2,4-triazol-1-yl)propanoate (CAS 1823402-86-3), molecular formula C7H10BrN3O2 and molecular weight 248.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(3-bromo-1H-1,2,4-triazol-1-yl)propanoate (C7H10BrN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
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.
