Abstract
The title compound, C19H19N3O2, is a Schiff base compound derived from 4-aminoantipyrine and 5-hydroxy-2-methylbenzaldehyde. The molecule adopts a trans configuration about the central C=N bond. There is an intramolecular O—H...N hydrogen bond. Futhermore, weak C—H...O hydrogen bonds lead to the formation of a chain developing parallel to the b axis.
