The monosodium salt is the biological stain 'Milling yellow 3G'. It has a role as a histological dye. It is an arenesulfonic acid, a member of azobenzenes, a heteroaryl hydroxy compound, a member of pyrazoles, a tosylate ester and a member of monochlorobenzenes. It is a conjugate acid of a Milling yellow 3G(1-)."}]
