Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 5-Fluoro-3-hydroxy-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (CAS 918645-89-3), a certified reference material (molecular formula C19H15FN2O2, MW 322.33 g/mol) for analytical method development and quality control.
The molecular framework of 5-Fluoro-3-hydroxy-3-methyl-3,4-dihydro-2H-[1,3'-biquinolin]-2-one (C19H15FN2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
