The structure of the title compound, C8H8ClNO, has already been reported [Subramanian (1966). Z. Kristallogr. 123, 222–234], but the positions of the H atoms have not been determined. It has now been refined with new intensity data to significantly higher precision and with all H atoms. The structure is closely related to N-(2-chlorophenyl)acetamide, N-(3-chlorophenyl)acetamide and other related amides, with similar bond parameters. The molecules are linked into chains through N—H⋯O hydrogen bonds.
