Chemical Structure
Description
The occurrence of Ethyl N-[2-cyano-5-(5-methyl-2-thienyl)-3-oxocyclohex-1-en-1-yl]glycinate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl N-[2-cyano-5-(5-methyl-2-thienyl)-3-oxocyclohex-1-en-1-yl]glycinate (CAS 1428139-73-4), a certified reference material (molecular formula C16H18N2O3S, MW 318.39 g/mol) for analytical method development and quality control.
Structurally, Ethyl N-[2-cyano-5-(5-methyl-2-thienyl)-3-oxocyclohex-1-en-1-yl]glycinate (C16H18N2O3S) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 318.39 g/mol, it falls into the moderately-high-molecular-weight range. 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 N-[2-cyano-5-(5-methyl-2-thienyl)-3-oxocyclohex-1-en-1-yl]glycinate 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.
