Chemical Structure
Description
The occurrence of 2-(4-(4-Bromophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)acetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-(4-Bromophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)acetic acid (CAS 339018-24-5), molecular formula C10H8BrN3O3 and molecular weight 298.09 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-(4-Bromophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)acetic acid (C10H8BrN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
