It is one of two of monochlorinated anthraquinone isomers. The compound is prepared by diacylation of chlorobenzene with phthalic anhydride, a standard route to anthraquinones. Heating 2-chloroanthraquinone under pressure with ammonia gives 2-aminoanthraquinone, which in turn is a precursor to indanthrone, a commercial blue dye.10.1002/14356007.a02_355 Anthraquinone Dyes and Intermediates Ullmann's Encyclopedia of Industrial Chemistry 2000 Bien Hans-Samuel Stawitz Josef Wunderlich Klaus 3527306730 References Category:Anthraquinone dyes Category:Chloroarenes
