Chemical Structure
Description
2,6-Dichloro-3-(4-trifluoromethylphenyl)-propiophenone (CAS 898749-92-3) is a high-purity analytical reference standard with the molecular formula C16H11Cl2F3O and a molecular weight of 347.16 g/mol.
2,6-Dichloro-3-(4-trifluoromethylphenyl)-propiophenone (C16H11Cl2F3O) 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. 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.
