Chemical Structure

2H-Pyrazolo[3,4-b]pyrazine CAS 24977-38-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2H-Pyrazolo[3,4-b]pyrazine (CAS 24977-38-6), a certified reference material (molecular formula C5H4N4, MW 120.11 g/mol) for analytical method development and quality control.

Structurally, 2H-Pyrazolo[3,4-b]pyrazine (C5H4N4) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 120.11 g/mol, it falls into the low-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).

As a certified reference material (CRM), 2H-Pyrazolo[3,4-b]pyrazine 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.
