4-(Pyrazin-2-yl)benzonitrile CAS 143526-42-5

Description

4-(Pyrazin-2-yl)benzonitrile (CAS 143526-42-5), molecular formula C11H7N3 and molecular weight 181.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H7N3, 4-(Pyrazin-2-yl)benzonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 181.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-(Pyrazin-2-yl)benzonitrile 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.
