2-Chloroanthraquinone is an organic compound with the formula C₁₄H₇O₂Cl. 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.^[1]
