8-Chloro-1-iodo-3-isopropylimidazo[1,5-a]pyrazine (CAS 1320266-92-9), molecular formula C9H9ClIN3 and molecular weight 321.55 g/mol, is a CATO reference standard with documented purity and traceability.
8-Chloro-1-iodo-3-isopropylimidazo[1,5-a]pyrazine (C9H9ClIN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine 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.
