Description
Alizarin yellow crystallizes as orange-brown needles from a dilute glacial Acetic acid solution. Developed in 1887 by R. Nietzki, it became 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.
Synonyms and Related Terms
Mordant Yellow 1; CI 14030; alizarine yellow R; p-nitrophenylazosalicylate acid; 2-hydroxy-5-[(4-nitrophenyl)azo]benzoic acid; amarilo de alizarina (Esp.); jaune d'alizarine (Fr.); giallo d'alizarina (It.); amarelo de alizarina (Port.)
