The disodium salt is the biological stain 'lissamine fast yellow'. It has a role as an allergen, a food colouring and a histological dye. It is a member of azobenzenes, a member of pyrazoles, a dichlorobenzene, a heteroaryl hydroxy compound and an arenesulfonic acid. It is a conjugate acid of a lissamine fast yellow(2-)."}]
