Chemical Structure
Description
As a certified reference material (CRM), 1H,4H,7H,8H-imidazo[4,5-d][1,3]diazepin-8-one hydrochloride 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.
1H,4H,7H,8H-imidazo[4,5-d][1,3]diazepin-8-one hydrochloride (CAS 71222-44-1) is a high-purity analytical reference standard with the molecular formula C6H10N4OHCl and a molecular weight of 190.63 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1H,4H,7H,8H-imidazo[4,5-d][1,3]diazepin-8-one hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.63 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.
