Usage

Description

MORDANT BROWN 4 is a dark red to light brown chemical compound that is soluble in water, producing a yellow-red color. It is also soluble in Cellosolve, slightly soluble in ethanol and acetone, and insoluble in other organic solvents. When exposed to concentrated sulfuric acid, it turns brilliant red, and upon dilution, there is a small change in color. In concentrated nitric acid, it forms an amber solution, and in a dilute sodium hydroxide solution, it results in a red-brown solution.
