2-(2-Methoxyphenyl)-1,3-thiazole-5-carboxylic acid CAS 920441-07-2

Description

The molecular framework of 2-(2-Methoxyphenyl)-1,3-thiazole-5-carboxylic acid (C11H9NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-(2-Methoxyphenyl)-1,3-thiazole-5-carboxylic acid (CAS 920441-07-2) is a high-purity analytical reference standard with the molecular formula C11H9NO3S and a molecular weight of 235.26 g/mol.

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.
