Description
Compared with other compounds in its class, the molecular weight of 286.30 g/mol gives (2E)-1-(2,5-Dimethoxyphenyl)-3-(2-fluorophenyl)prop-2-en-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2E)-1-(2,5-Dimethoxyphenyl)-3-(2-fluorophenyl)prop-2-en-1-one (CAS 1004035-72-6), molecular formula C17H15FO3 and molecular weight 286.30 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-1-(2,5-Dimethoxyphenyl)-3-(2-fluorophenyl)prop-2-en-1-one (C17H15FO3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
