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-HO hydrogen bonds.
