Chemical Structure
Description
The occurrence of 3-((4-Bromophenoxy)methyl)-4-methoxybenzoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-((4-Bromophenoxy)methyl)-4-methoxybenzoic acid (CAS 438221-51-3) is a high-purity analytical reference standard with the molecular formula C15H13BrO4 and a molecular weight of 337.17 g/mol.
The molecular framework of 3-((4-Bromophenoxy)methyl)-4-methoxybenzoic acid (C15H13BrO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
