There are two independent molecules in the asymmetric unit of the title compound, C15H10ClNO2, which differ in the dihedral angles between the mean planes of the phenyl ring and the 4-chloroindoline-2,3-dione ring system [59.48 (9) and 79.0 (1)°]. In the crystal, molecules are linked through C-HO hydrogen bonds, forming polymeric chains in .
