Chemical Structure
Description
Structurally, 2-Amino-6-chloropyrazine 6-chloropyrazin-2-amine 2-chloro-6-aminopyrazine 6-chloro-pyrazin-2-ylamine 2-amino-6-chloro-pyrazine 6-chloropyrazin-2-ylamine 33332-28-4 (C4H4ClN3) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 129.55 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).
