Chemical Structure
Description
Structurally, 3,5-Dimethyl-3H-[1,2,3]triazolo[4,5-b]pyridine (C7H8N4) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 148.17 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
