Chemical Structure

2H-Naphtho[1,2-d]triazole-5-sulfonic acid, 2-[4-[2-(4-nitro-2-sulfophenyl)ethenyl]-3-sulfophenyl]-, sodium salt (1:3) CAS 69178-37-6 chemical structure

Description

Based on its molecular formula C24H13N4O11S3Na, 2H-Naphtho[1,2-d]triazole-5-sulfonic acid, 2-[4-[2-(4-nitro-2-sulfophenyl)ethenyl]-3-sulfophenyl]-, sodium salt (1:3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 652.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
