In the title compound, C11H7ClO3, a chlorinated and methylated 3-formylchromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0670 Å), with the largest deviation from the least-squares plane [0.2349 (17) Å] being for the pyran carbonyl O atom. In the crystal, molecules are linked through π–π stacking interactions along theaaxis [centroid–centroid distance between the pyran rings = 3.824 (6) Å] and two stacks are connected by type I halogen–halogen interactions between the Cl atoms [Cl...Cl = 3.397 (3) Å].
