Chemical Structure

2,5-Di(1H-pyrazol-4-yl)benzonitrile CAS 1984799-71-4 chemical structure

Description

The molecular framework of 2,5-Di(1H-pyrazol-4-yl)benzonitrile (C13H9N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,5-Di(1H-pyrazol-4-yl)benzonitrile (CAS 1984799-71-4) is a high-purity analytical reference standard with the molecular formula C13H9N5 and a molecular weight of 235.24 g/mol.

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.

CATO manufactures 2,5-Di(1H-pyrazol-4-yl)benzonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
