Chemical Structure

Imidazo[1,5-a]pyrazin-8(7H)-one CAS 56468-21-4 chemical structure

Description

Imidazo[1,5-a]pyrazin-8(7H)-one (CAS 56468-21-4), molecular formula C6H5N3O and molecular weight 135.12 g/mol, is a CATO reference standard with documented purity and traceability.

Imidazo[1,5-a]pyrazin-8(7H)-one (C6H5N3O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Imidazo[1,5-a]pyrazin-8(7H)-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.
