CATO supplies 6-Chloro-1-(phenylsulfonyl)-1H-indole-2-carboxamide (CAS 540740-48-5), a certified reference material (molecular formula C15H11ClN2O3S, MW 334.78 g/mol) for analytical method development and quality control.
6-Chloro-1-(phenylsulfonyl)-1H-indole-2-carboxamide (C15H11ClN2O3S) 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.
