8-chloro-4H,5H-imidazo[1,5-a]quinoxalin-4-one CAS 1334331-42-8 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 8-chloro-4H,5H-imidazo[1,5-a]quinoxalin-4-one.

CATO supplies 8-chloro-4H,5H-imidazo[1,5-a]quinoxalin-4-one (CAS 1334331-42-8), a certified reference material (molecular formula C10H16ClN3O, MW 229.71 g/mol) for analytical method development and quality control.

Structurally, 8-chloro-4H,5H-imidazo[1,5-a]quinoxalin-4-one (C10H16ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.71 g/mol, it falls into the medium-molecular-weight range. 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), 8-chloro-4H,5H-imidazo[1,5-a]quinoxalin-4-one 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.
