Chemical Structure
Description
The occurrence of 2-(2-((4-Bromophenyl)amino)-2-oxoethoxy)benzoic acid is closely related to a flavonoid core, 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-(2-((4-Bromophenyl)amino)-2-oxoethoxy)benzoic acid (CAS 329220-18-0) is a high-purity analytical reference standard with the molecular formula C15H12BrNO4 and a molecular weight of 350.16 g/mol.
The molecular framework of 2-(2-((4-Bromophenyl)amino)-2-oxoethoxy)benzoic acid (C15H12BrNO4) is characterized by a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2-(2-((4-Bromophenyl)amino)-2-oxoethoxy)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
