Chemical Structure
Description
The occurrence of 8-Chloro-5-fluoro-3-(trifluoromethyl)quinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
8-Chloro-5-fluoro-3-(trifluoromethyl)quinoline (CAS 1227293-41-5) is a high-purity analytical reference standard with the molecular formula C10H4ClF4N and a molecular weight of 249.59 g/mol.
8-Chloro-5-fluoro-3-(trifluoromethyl)quinoline (C10H4ClF4N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
