Description

The occurrence of 2-(5-Methyl-1H-pyrazol-1-yl)acetonitrile is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(5-Methyl-1H-pyrazol-1-yl)acetonitrile (CAS 218921-02-9), molecular formula C6H7N3 and molecular weight 121.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(5-Methyl-1H-pyrazol-1-yl)acetonitrile (C6H7N3) 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. 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), 2-(5-Methyl-1H-pyrazol-1-yl)acetonitrile 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.
