[1,2,4]Triazolo[1,5-a]pyrazine-8-carbonitrile CAS 86805-31-4

Description

As a certified reference material (CRM), [1,2,4]Triazolo[1,5-a]pyrazine-8-carbonitrile 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.

[1,2,4]Triazolo[1,5-a]pyrazine-8-carbonitrile (CAS 86805-31-4), molecular formula C6H3N5 and molecular weight 145.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1,2,4]Triazolo[1,5-a]pyrazine-8-carbonitrile (C6H3N5) is characterized by a nitrile group, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
