Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 423.52 g/mol gives Ethyl 5-phenyl-2-(4-(m-tolyloxy)butanamido)thiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 5-phenyl-2-(4-(m-tolyloxy)butanamido)thiophene-3-carboxylate (CAS 459415-15-7), molecular formula C24H25NO4S and molecular weight 423.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 5-phenyl-2-(4-(m-tolyloxy)butanamido)thiophene-3-carboxylate (C24H25NO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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), Ethyl 5-phenyl-2-(4-(m-tolyloxy)butanamido)thiophene-3-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.
