Chemical Structure
Description
The occurrence of 4-Chloro-N-(6-chloro-4-(trifluoromethyl)pyridin-2-yl)-N-methylbenzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Chloro-N-(6-chloro-4-(trifluoromethyl)pyridin-2-yl)-N-methylbenzenesulfonamide (CAS 1311279-15-8), a certified reference material (molecular formula C13H9Cl2F3N2O2S, MW 385.19 g/mol) for analytical method development and quality control.
4-Chloro-N-(6-chloro-4-(trifluoromethyl)pyridin-2-yl)-N-methylbenzenesulfonamide (C13H9Cl2F3N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
