Chemical Structure
Description
The occurrence of (3Z)-3-(3,4-Dimethoxyphenyl)-4-[(4-phenoxyphenyl)amino]but-3-en-2-one is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3Z)-3-(3,4-Dimethoxyphenyl)-4-[(4-phenoxyphenyl)amino]but-3-en-2-one (CAS 339017-40-2), molecular formula C24H23NO4 and molecular weight 389.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3Z)-3-(3,4-Dimethoxyphenyl)-4-[(4-phenoxyphenyl)amino]but-3-en-2-one (C24H23NO4) is characterized by a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
