Developed in 1887 by R. Nietzki, it was the first azo mordant dye. Alizarin yellow produces a dull yellow-brown, transparent pigment when precipitated on an inert base that has poorer color stability than alizarin. The sodium salt of alizarin yellow is used as an aqueous acid-base indicator. It changes from yellow at pH 10.2 to red at pH 12.0. == Synonym...")
