The disodium salt is the histological dye 'Sirius red 4B'. It has a role as a fluorochrome, a histological dye, an environmental contaminant and a poison. It is a member of azobenzenes, a bis(azo) compound, a member of naphthols, a naphthalenesulfonic acid and a member of benzamides. It is a conjugate acid of a Sirius red 4B(2-)."}]
