azo dyes

dyes in which the azo group is the chromophore and joins benzene or naphthalene rings; they include a large number of biologic stains (for example, Congo red and oil red O); also used clinically to promote epithelial growth in the treatment of ulcers, burns, and other wounds; many have anticoagulant action.
