A heterocyclic aromatic compound containing a benzene ring fused with a nitrogen-containing ring, a type of diazine or nitrogen heterocycle.
From 'benz-' (benzene) + 'azine' (from 'az-' meaning nitrogen + '-ine' suffix). This term emerged as chemists systematically studied fused-ring systems containing heteroatoms in the late 1800s.
Benzazine compounds show up in some medicines and natural products—by swapping a carbon atom for nitrogen in a benzene ring, you get dramatically different properties, which is why nature uses these tricks so often.
