Chemical Structure
Description
CATO supplies Enoxacin-D8 hydrate (CAS CATO-CCAD301257), a certified reference material (molecular formula C15H9D8FN4O3H2O, MW 346.39 g/mol) for analytical method development and quality control.
Enoxacin-D8 hydrate (C15H9D8FN4O3H2O) contains deuterium isotope labeling, a flavonoid 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.
