Chemical Structure

5-(3-Fluorophenyl)thiophene-2-carboxylic acid CAS 893733-12-5 chemical structure

Description

The occurrence of 5-(3-Fluorophenyl)thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(3-Fluorophenyl)thiophene-2-carboxylic acid (CAS 893733-12-5) is a high-purity analytical reference standard with the molecular formula C11H7FO2S and a molecular weight of 222.24 g/mol.

Based on its molecular formula C11H7FO2S, 5-(3-Fluorophenyl)thiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
