Description
Compared with other compounds in its class, the molecular weight of 341.58 g/mol gives 5-Bromo-2-[(2-chlorobenzyl)oxy]benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-2-[(2-chlorobenzyl)oxy]benzoic acid (CAS 62176-33-4), a certified reference material (molecular formula C14H10BrClO3, MW 341.58 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-2-[(2-chlorobenzyl)oxy]benzoic acid (C14H10BrClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 341.58 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
