Chemical Structure
Description
The occurrence of 3-[3-(carboxymethyl)phenyl]-5-fluorobenzoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[3-(carboxymethyl)phenyl]-5-fluorobenzoic acid (CAS 1393442-01-7) is a high-purity analytical reference standard with the molecular formula C15H11FO4 and a molecular weight of 274.24 g/mol.
The molecular framework of 3-[3-(carboxymethyl)phenyl]-5-fluorobenzoic acid (C15H11FO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
