Chemical Structure

2-Ethoxy-3-(2-((5-methyl-2-phenyloxazol-4-yl)methyl)benzofuran-5-yl)propanoic acid CAS 140129-67-5 chemical structure

Description

The occurrence of 2-Ethoxy-3-(2-((5-methyl-2-phenyloxazol-4-yl)methyl)benzofuran-5-yl)propanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Ethoxy-3-(2-((5-methyl-2-phenyloxazol-4-yl)methyl)benzofuran-5-yl)propanoic acid (CAS 140129-67-5), a certified reference material (molecular formula C24H23NO5, MW 405.44 g/mol) for analytical method development and quality control.

The molecular framework of 2-Ethoxy-3-(2-((5-methyl-2-phenyloxazol-4-yl)methyl)benzofuran-5-yl)propanoic acid (C24H23NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
