Chemical Structure
Description
The occurrence of (1E)-1-[(2,4-Dichlorophenyl)amino]-2-[(2,4-dichlorophenyl)carbamoyl]-2-[(1E)-(methoxyimino)methyl]eth-1-en-1-yl acetate 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.
(1E)-1-[(2,4-Dichlorophenyl)amino]-2-[(2,4-dichlorophenyl)carbamoyl]-2-[(1E)-(methoxyimino)methyl]eth-1-en-1-yl acetate (CAS 338964-98-0), molecular formula C19H15Cl4N3O4 and molecular weight 491.15 g/mol, is a CATO reference standard with documented purity and traceability.
(1E)-1-[(2,4-Dichlorophenyl)amino]-2-[(2,4-dichlorophenyl)carbamoyl]-2-[(1E)-(methoxyimino)methyl]eth-1-en-1-yl acetate (C19H15Cl4N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
