Acid red 88 explained

Acid red 88 is an azo dye. Due to its intense colour, solid samples appear almost black. It is used to dye cotton textiles red.^[1] A closely related acid dye is Acid Red 13.

Preparation and use

It can be obtained by azo coupling of naphthionic acid and 2-naphthol. Instead of crystallising, it vitrifies when cooled or salted out of the solution.

This compound is used in the textile industry as a dye.^[2] It can also be used for research in photocatalysis (as degradation object).^[3]
