Chemical Structure
Description
Ethyl 4-[4-(4-chlorophenyl)piperazin-1-yl]-6-(trifluoromethyl)quinoline-3-carboxylate (C23H21ClF3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
Ethyl 4-[4-(4-chlorophenyl)piperazin-1-yl]-6-(trifluoromethyl)quinoline-3-carboxylate (CAS 338748-33-7) is a high-purity analytical reference standard with the molecular formula C23H21ClF3N3O2 and a molecular weight of 463.88 g/mol.
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.
