Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(6-amino-3-fluoro-5-(3-hydroxyazetidin-1-yl)pyridin-2-yl)-6-fluoro-7-(3-hydroxyazetidin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid.
1-(6-amino-3-fluoro-5-(3-hydroxyazetidin-1-yl)pyridin-2-yl)-6-fluoro-7-(3-hydroxyazetidin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (CAS CATO-C4X-263728), molecular formula C21H19F2N5O5 and molecular weight 459.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(6-amino-3-fluoro-5-(3-hydroxyazetidin-1-yl)pyridin-2-yl)-6-fluoro-7-(3-hydroxyazetidin-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 459.40 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.
