Chemical Structure
Description
Sodium 3-((4-amino-3-methoxyphenyl)diazenyl)benzenesulfonate (C13H12N3O4SNa) 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).
