6-Bromo-1H-[1,2,3]triazolo[4,5-b]pyrazine (CAS 1260665-33-5) is a high-purity analytical reference standard with the molecular formula C4H2BrN5 and a molecular weight of 200.00 g/mol.
6-Bromo-1H-[1,2,3]triazolo[4,5-b]pyrazine (C4H2BrN5) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
