Chemical Structure
Description
The occurrence of 2-Bromo-6-methylpyrazino[2,3-b]pyrazine is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-6-methylpyrazino[2,3-b]pyrazine (CAS 91225-51-3), molecular formula C7H5BrN4 and molecular weight 225.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 2-Bromo-6-methylpyrazino[2,3-b]pyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
