An organic compound containing a five-membered ring with nitrogen atoms, derived from glyoxal and related to imidazole chemistry.
From 'glyoxal' + '-in' (chemical suffix for nitrogen-containing compounds). This term emerged as synthetic chemists created new ring-structured molecules in the early 1900s.
Glyoxalin and its derivatives are the basis for important pharmaceutical compounds—the ring structure was so useful that chemists kept making variations, leading to dozens of modern drugs!
