Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2E)-1-(3,4-Dichlorophenyl)-3-(2-fluorophenyl)prop-2-en-1-one (CAS 386216-25-7), molecular formula C15H9Cl2FO and molecular weight 295.14 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-1-(3,4-Dichlorophenyl)-3-(2-fluorophenyl)prop-2-en-1-one (C15H9Cl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
