Chemical Structure
Description
The occurrence of Ethyl 4-(4-(2,4-dichlorophenoxy)butanamido)benzoate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-(4-(2,4-dichlorophenoxy)butanamido)benzoate (CAS 329938-35-4), molecular formula C19H19Cl2NO4 and molecular weight 396.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4-(4-(2,4-dichlorophenoxy)butanamido)benzoate (C19H19Cl2NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
