Deskripsi
In the title compound, C22H26N4O2, the phenyl ring and hydroxybenzene group are twisted with respect to the central pyrazolone ring, making dihedral angles of 54.05 (5) and 21.80 (6)°, respectively. One of the ethyl groups is disordered over two positions with site occupancies of 0.872 (6) and 0.128 (6). The molecular structure features short intramolecular O—H...N and C—H...O contacts. The crystal packing exhibits weak intermolecular C—H...O and C—H...π interactions.
