Diaza
Diaza is a chemical term used in systematic nomenclature to indicate the presence of two nitrogen atoms in a molecule or substructure. It is formed from dia-, meaning double or two, and aza, from azote (nitrogen). In practice, diaza is used as a prefix in naming heterocyclic compounds and related frameworks to mark two nitrogen substitutions within an otherwise carbon-based skeleton.
In heterocyclic chemistry, diaza appears in the names of compound classes where two nitrogens occupy defined
Diaza-containing structures occur across areas of chemistry, including medicinal chemistry, coordination chemistry, and materials science. The
