Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-imidazo[4,5-f]quinoxalin-2-amine.
1H-imidazo[4,5-f]quinoxalin-2-amine (CAS 118175-25-0) is a high-purity analytical reference standard with the molecular formula C9H7N5 and a molecular weight of 185.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1H-imidazo[4,5-f]quinoxalin-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.19 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1H-imidazo[4,5-f]quinoxalin-2-amine 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.
