7-Chloro-N-(2-methoxyphenyl)-4-methyl-2-oxo-1,2-dihydroquinoline-6-sulfonamide CAS 1418265-80-1

Description

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.

7-Chloro-N-(2-methoxyphenyl)-4-methyl-2-oxo-1,2-dihydroquinoline-6-sulfonamide (CAS 1418265-80-1) is a high-purity analytical reference standard with the molecular formula C17H15ClN2O4S and a molecular weight of 378.83 g/mol.

7-Chloro-N-(2-methoxyphenyl)-4-methyl-2-oxo-1,2-dihydroquinoline-6-sulfonamide (C17H15ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
