    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 581235

CAS#: 1658-56-6

Description: Acid red 88 is an anionic dye with potentially useful photocatalytic research applications. Acid red 88 has been used to determine the effect of Au deposition on ZnO photocatalytic activity under visible light. Additionally, the photocatalyst Au-TiO2 was used for photocatalytic degradation of Acid red 88. Acid red 88 is a azo dye. Due to its intense colour, solid samples appear almost black. It is used to dye cotton textiles red. A closely related acid dye is Acid Red 13.
