Chemical Structure

2-Methyl-5-(thiophen-2-yl)furan-3-carboxylic acid CAS 651005-90-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 208.23 g/mol gives 2-Methyl-5-(thiophen-2-yl)furan-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-5-(thiophen-2-yl)furan-3-carboxylic acid (CAS 651005-90-2) is a high-purity analytical reference standard with the molecular formula C10H8O3S and a molecular weight of 208.23 g/mol.

The molecular framework of 2-Methyl-5-(thiophen-2-yl)furan-3-carboxylic acid (C10H8O3S) is characterized by a sulfone group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
