Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.77 g/mol gives 5-Chloro-2-methoxy-N-(pyridin-4-ylmethyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-2-methoxy-N-(pyridin-4-ylmethyl)benzenesulfonamide (CAS 339360-57-5), molecular formula C13H13ClN2O3S and molecular weight 312.77 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-methoxy-N-(pyridin-4-ylmethyl)benzenesulfonamide (C13H13ClN2O3S) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
