1-Methyl-2-(4-methyl-phen-yl)-4-morpholinopyridazine-3,6(1H,2H)-dione
Abstract:
The structure analysis of the title compound, C(16)H(19)N(3)O(3), has been undertaken in order to facilitate the inter-pretation of (1)H and (13)C NMR data and to determine the position of the morpholine residue in this nucleophilic substitution product. The main result is that the morpholine group, with a chair conformation, is connected at the 4-position of the pyridazine ring. The benzene and pyridazine rings make a dihedral angle of 62.17 (5)°. Mol-ecules are linked into a two-dimensional network by non-classical C-H⋯O hydrogen bonds, in which O atoms serve as double or triple acceptors.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
