Chemical Structure
Description
7-Benzothiazolesulfonic acid, 2-[4-[[2-cyano-3-[4-[methyl(2-sulfoethyl)amino]phenyl]-1-oxo-2-propen-1-yl]amino]phenyl]-6-methyl-, sodium salt (C27H22N4O7S3Na) contains a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
