Ethyl 3-formyl-4H-thieno[3,2-b]pyrrole-5-carboxylate CAS 59958-28-0

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 3-formyl-4H-thieno[3,2-b]pyrrole-5-carboxylate (CAS 59958-28-0) is a high-purity analytical reference standard with the molecular formula C10H9NO3S and a molecular weight of 223.25 g/mol.

Based on its molecular formula C10H9NO3S, Ethyl 3-formyl-4H-thieno[3,2-b]pyrrole-5-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 223.25 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 3-formyl-4H-thieno[3,2-b]pyrrole-5-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.
