The pyrazole ring in the title compound, C25H19BrN2O2, is almost planar (r.m.s. deviation = 0.003 Å) and forms dihedral angles of 7.56 (13) and 56.48 (13)° with the N- and C-bound benzene rings, respectively. The prop-2-en-1-one residue has an E conformation about the C=C double bond [1.328 (4) Å] and is almost coplanar with the pyrazole ring [C—C—C—C torsion angle = −174.4 (3)°]. A twist between the prop-2-en-1-one unit and the terminal benzene ring is evident [C—C—C—C torsion angle = −15.4 (4)°]. In the crystal, molecules are consolidated into a three-dimensional architecture by C—H...O, C—H...π and π–π [centroid–centroid separation = 3.7597 (16) Å] interactions.
