Chemical Structure
Description
The occurrence of Ethyl 3-oxo-4-(thiophen-2-yl)butanoate 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 Ethyl 3-oxo-4-(thiophen-2-yl)butanoate (CAS 86728-40-7), a certified reference material (molecular formula C10H12O3S, MW 212.27 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H12O3S, Ethyl 3-oxo-4-(thiophen-2-yl)butanoate 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 212.27 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 3-oxo-4-(thiophen-2-yl)butanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
