Ethyl 5,6-dihydro-4h-cyclopenta[b]thiophene-2-carboxylate CAS 19282-44-1

Description

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.

Ethyl 5,6-dihydro-4h-cyclopenta[b]thiophene-2-carboxylate (CAS 19282-44-1), molecular formula C10H12O2S and molecular weight 196.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H12O2S, Ethyl 5,6-dihydro-4h-cyclopenta[b]thiophene-2-carboxylate 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 196.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Ethyl 5,6-dihydro-4h-cyclopenta[b]thiophene-2-carboxylate 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.
