Abstract: In the title compound, C9H6ClNO, the Cl atom deviates by 0.142 (1) Å from the quinoline ring mean plane (r.m.s. deviation = 0.013 Å). In the crystal, N-HO hydrogen bonds link the molecules into  C(4) chains. Aromatic - stacking interactions [shortest centroidcentroid distance = 3.685 (3) Å] are also observed.
