Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Oxo-4-(thiophen-3-yl)butanoic acid (CAS 1878-23-5) is a high-purity analytical reference standard with the molecular formula C8H8O3S and a molecular weight of 184.21 g/mol.

Based on its molecular formula C8H8O3S, 4-Oxo-4-(thiophen-3-yl)butanoic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 184.21 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).
