Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 373.47 g/mol gives Methyl (2Z)-3-[(4-methylphenyl)amino]-2-[4-(propan-2-yl)benzenesulfonyl]prop-2-enoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl (2Z)-3-[(4-methylphenyl)amino]-2-[4-(propan-2-yl)benzenesulfonyl]prop-2-enoate (CAS 1327181-17-8), molecular formula C20H23NO4S and molecular weight 373.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl (2Z)-3-[(4-methylphenyl)amino]-2-[4-(propan-2-yl)benzenesulfonyl]prop-2-enoate (C20H23NO4S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
