Abstract: There are two independent mol­ecules (A and B) in the asymmetric unit of the title compound, C14H12ClNO3. The mean planes of the methyl ester unit (Cmeth­yl-O-C=O; r.m.s. deviation = 0.051 Å for mol­ecule A and 0.016 Å for mol­ecule B) and the chloro­quilonine ring system (r.m.s. deviation = 0.023 Å for mol­ecule A and 0.014 Å for mol­ecule B) form dihedral angles of 63.5 (1)° in mol­ecule A and 78.1 (1)° in mol­ecule B. The main difference between the two independent mol­ecules is reflected in the (H)O-C-C=C(H2) torsion angle which is -109.7 (2)° in mol­ecule A and 10.6 (2)° in mol­ecule B. An intra­molecular O-H...O hydrogen bond is observed in mol­ecule A. In the crystal, mol­ecules A and B are linked into pairs via bifurcated O-H...(N,Cl) hydrogen bonds and a weak C-H...O hydrogen bond links pairs of mol­ecules into chains along [100].
