Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 139.10 g/mol gives 2,5-Difluorobenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Difluorobenzonitrile (CAS 64248-64-2) is a high-purity analytical reference standard with the molecular formula C7H3F2N and a molecular weight of 139.10 g/mol.
The molecular framework of 2,5-Difluorobenzonitrile (C7H3F2N) is characterized by a nitrile group, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Difluorobenzonitrile 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.
