Chemical Structure
Description
The occurrence of Methyl (2Z)-2-(4-ethoxybenzenesulfonyl)-3-(phenylamino)prop-2-enoate is closely related to a flavonoid core, 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 Methyl (2Z)-2-(4-ethoxybenzenesulfonyl)-3-(phenylamino)prop-2-enoate (CAS 1327174-34-4), a certified reference material (molecular formula C18H19NO5S, MW 361.41 g/mol) for analytical method development and quality control.
Structurally, Methyl (2Z)-2-(4-ethoxybenzenesulfonyl)-3-(phenylamino)prop-2-enoate (C18H19NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 361.41 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
