Description
Compared with other compounds in its class, the molecular weight of 225.26 g/mol gives Thieno[3,2-c]pyridine-5(4H)-carboxylic acid, 6,7-dihydro-7-oxo-, ethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Thieno[3,2-c]pyridine-5(4H)-carboxylic acid, 6,7-dihydro-7-oxo-, ethyl ester (CAS 2090010-35-6), molecular formula C10H11NO3S and molecular weight 225.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Thieno[3,2-c]pyridine-5(4H)-carboxylic acid, 6,7-dihydro-7-oxo-, ethyl ester (C10H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 225.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), Thieno[3,2-c]pyridine-5(4H)-carboxylic acid, 6,7-dihydro-7-oxo-, ethyl ester 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.
