Hazard Information

Chemical Properties

Soluble in water, its aqueous solution is magenta, which turns wine red upon addition of concentrated hydrochloric acid. Adding concentrated sodium hydroxide solution turns it to jujube red. Slightly soluble in ethanol, it is magenta. In concentrated sulfuric acid, it is dark purple, which turns pink upon dilution.

Uses

C.I. Acid red 154 is an acid red dye that can be adsorbed and removed by bentone clay.

Preparation

4-(1-(4-Amino-3-methylphenyl)cyclohexyl)-2-methylbenzenamine double nitriding, and 4,6-Dihydroxynaphthalene-1-sulfonic acid?(2 Moore) coupled.
