Chemical Structure

Methyl (2Z)-2-(4-tert-butylbenzenesulfonyl)-3-[(4-methoxyphenyl)amino]prop-2-enoate CAS 1327178-62-0 chemical structure

Description

The occurrence of Methyl (2Z)-2-(4-tert-butylbenzenesulfonyl)-3-[(4-methoxyphenyl)amino]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.

Methyl (2Z)-2-(4-tert-butylbenzenesulfonyl)-3-[(4-methoxyphenyl)amino]prop-2-enoate (CAS 1327178-62-0) is a high-purity analytical reference standard with the molecular formula C21H25NO5S and a molecular weight of 403.49 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl (2Z)-2-(4-tert-butylbenzenesulfonyl)-3-[(4-methoxyphenyl)amino]prop-2-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
