Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Azido-3,4,8-trimethyl-3H-imidazo[4,5-f]quinoxaline (CAS 210100-58-6), molecular formula C12H11N7 and molecular weight 253.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-Azido-3,4,8-trimethyl-3H-imidazo[4,5-f]quinoxaline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 2-Azido-3,4,8-trimethyl-3H-imidazo[4,5-f]quinoxaline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
