Abstract

The title compound, C16H15F3N2O3, is composed of a 3-(tri­fluoro­methyl)­phenyl ring and a pyridazinone ring, which are approximately coplanar, and an ethyl acetate group on the pyridazinone ring. In the crystal structure, centrosymmetric­ally related mol­ecules form dimers through non-classical intermolecular C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]
