TCI C0550 Congo Red (CAS 573-58-0) is a classical direct azo dye offered for research and experimental use. It is widely applied in histology for amyloid staining, in microbiology for screening cellulose-degrading activity on agar plates, and as an acid–base indicator with a clear colour transition in the acidic range. Its well-defined azo structure also makes it a common model dye in adsorption, photocatalysis, and dye-wastewater studies. Handle the powder with gloves and eye protection, and keep the container tightly closed in a cool, dry place away from direct light.
