Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Fluoro-2-(p-tolyl)quinoline-4-carboxylic acid, 97% (CAS 18060-42-9), molecular formula C17H12FNO2 and molecular weight 281.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 6-Fluoro-2-(p-tolyl)quinoline-4-carboxylic acid, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
