Chemical Structure
Description
289483-69-8 TVH5K7949N N-(3-cyano-4-methyl-1H-indol-7-yl)-3-cyanobenzene-sulfonamide Benzenesulfonamide, 3-cyano-N-(3-cyano-4-methyl-1H-indol-7-yl)- 3-Cyano-N-(3-cyano-4-methyl-1H-indole-7-yl)benzensulfonamide E 7820 E7820 UNII-TVH5K7949N (C17H12N4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
