Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4,5,6-Tetrachloronicotinonitrile.
2,4,5,6-Tetrachloronicotinonitrile (CAS 17824-82-7) is a high-purity analytical reference standard with the molecular formula C6Cl4N2 and a molecular weight of 241.89 g/mol.
The molecular framework of 2,4,5,6-Tetrachloronicotinonitrile (C6Cl4N2) 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. 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.
As a certified reference material (CRM), 2,4,5,6-Tetrachloronicotinonitrile 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.
