Chemical Structure
Description
The occurrence of 3-((3,4-Dimethylphenyl)sulfonyl)-6,7-difluoro-1-methylquinolin-4(1H)-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-((3,4-Dimethylphenyl)sulfonyl)-6,7-difluoro-1-methylquinolin-4(1H)-one (CAS 1326863-34-6), a certified reference material (molecular formula C18H15F2NO3S, MW 363.38 g/mol) for analytical method development and quality control.
3-((3,4-Dimethylphenyl)sulfonyl)-6,7-difluoro-1-methylquinolin-4(1H)-one (C18H15F2NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
