Abstract:
The mol-ecule of the title compound, C(14)H(19)N(3)O(7)·0.5H(2)O, exhibits an E conformation about the C=N double bond. The water mol-ecule possesses crystallographically imposed twofold symmetry. In the crystal structure, the mol-ecules are connected by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.

01:19Aldehydes and Ketones with Alcohols: Hemiacetal Formation
Similar to water, alcohols can add to the carbonyl carbon of the aldehydes and ketones. The addition of one molecule of alcohol to the carbonyl compound forms the hemiacetal or half acetal. As depicted below, in a hemiacetal, the carbon is directly linked to an OH and OR group.
02:34Regioselectivity and Stereochemistry of Acid-Catalyzed Hydration
The rate of acid-catalyzed hydration of alkenes depends on the alkene's structure, as the presence of alkyl substituents at the double bond can significantly influence the rate.
