Description
1-Cyclopropyl-6-fluoro-7-(3-((isopropylamino)methyl)pyrrolidin-1-yl)-4-oxo-8-(trifluoromethyl)-1,4-dihydroquinoline-3-carboxylic acid (CAS 146981-05-7), molecular formula C22H25F4N3O3 and molecular weight 455.45 g/mol, is a CATO reference standard with documented purity and traceability.
1-Cyclopropyl-6-fluoro-7-(3-((isopropylamino)methyl)pyrrolidin-1-yl)-4-oxo-8-(trifluoromethyl)-1,4-dihydroquinoline-3-carboxylic acid (C22H25F4N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
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.
