Chemical Structure

5-(4-Methoxybenzyl)-2-furoic acid CAS 3988-92-9 chemical structure

Description

The occurrence of 5-(4-Methoxybenzyl)-2-furoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(4-Methoxybenzyl)-2-furoic acid (CAS 3988-92-9), a certified reference material (molecular formula C13H12O4, MW 232.23 g/mol) for analytical method development and quality control.

The molecular framework of 5-(4-Methoxybenzyl)-2-furoic acid (C13H12O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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.
