The title compound, C11H10O2, belongs to the class of 4-benzopyrones (also known as chromen-4-ones) with potentially diverse pharmacological activities. It was synthesized by acylation of 2-hydroxy-4-methylacetophenone with ethyl acetate in the presence of sodium hydride and subsequent cyclization by hydrochloric acid. All non-H atoms of the substituted bicyclic molecule are coplanar within 0.03 Å. C—H…O interactions [C…O = 3.272 (5) Å] link neighbouring molecules related by the 21 axis.
