A chemical compound containing a benzene ring fused to a six-membered ring with three nitrogen atoms, used in pharmaceutical and materials research.
From 'benzo-' (benzene) + 'triazine' (six-membered ring with three nitrogens; from 'tri-' meaning three, plus '-azine' from 'aza' meaning nitrogen-containing). Systematically named in the mid-20th century as heterocyclic chemistry expanded.
Benzotriazines are particularly useful as UV absorbers in sunscreen and plastic protection—those three nitrogen atoms are like tiny electron sponges that soak up harmful ultraviolet radiation and release it as harmless heat, which is why you'll find them in many commercial products.
