Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 290.76 g/mol gives 4-Chloro-3-(2,5-dimethylphenyl)-3-fluoropropiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-3-(2,5-dimethylphenyl)-3-fluoropropiophenone (CAS 898753-69-0) is a high-purity analytical reference standard with the molecular formula C17H16ClFO and a molecular weight of 290.76 g/mol.
4-Chloro-3-(2,5-dimethylphenyl)-3-fluoropropiophenone (C17H16ClFO) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. 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.
