3-(2,5-Dimethyl-1H-pyrrol-1-yl)-4,5-dimethylthiophene-2-carboxylic acid CAS 690990-60-4 chemical structure

Description

The occurrence of 3-(2,5-Dimethyl-1H-pyrrol-1-yl)-4,5-dimethylthiophene-2-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(2,5-Dimethyl-1H-pyrrol-1-yl)-4,5-dimethylthiophene-2-carboxylic acid (CAS 690990-60-4) is a high-purity analytical reference standard with the molecular formula C13H15NO2S and a molecular weight of 249.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(2,5-Dimethyl-1H-pyrrol-1-yl)-4,5-dimethylthiophene-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
