methyl 3-hydroxy-4-methylthiophene-2-carboxylate CAS 32711-57-2

Description

The occurrence of methyl 3-hydroxy-4-methylthiophene-2-carboxylate is closely related to a sulfone group, 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 methyl 3-hydroxy-4-methylthiophene-2-carboxylate (CAS 32711-57-2), a certified reference material (molecular formula C7H8O3S, MW 172.20 g/mol) for analytical method development and quality control.

Structurally, methyl 3-hydroxy-4-methylthiophene-2-carboxylate (C7H8O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 172.20 g/mol, it falls into the medium-molecular-weight range. 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.
