Description

The occurrence of 6-Chloro-2-methyl-[1,2,4]triazolo[1,5-a]pyrazine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-2-methyl-[1,2,4]triazolo[1,5-a]pyrazine (CAS 20914-72-1), molecular formula C6H5ClN4 and molecular weight 168.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Chloro-2-methyl-[1,2,4]triazolo[1,5-a]pyrazine (C6H5ClN4) is characterized by a nitrile group, chlorine substitution, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 6-Chloro-2-methyl-[1,2,4]triazolo[1,5-a]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.
