Chemical Structure
Description
The occurrence of (2E)-1-(2,4-Dichlorophenyl)-3-(4-ethoxyphenyl)prop-2-en-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2E)-1-(2,4-Dichlorophenyl)-3-(4-ethoxyphenyl)prop-2-en-1-one (CAS 1486549-12-5), molecular formula C17H14Cl2O2 and molecular weight 321.20 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-1-(2,4-Dichlorophenyl)-3-(4-ethoxyphenyl)prop-2-en-1-one (C17H14Cl2O2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
