Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-6-(3-chlorophenyl)-4-(trifluoromethyl)pyridine-3-carbonitrile (CAS 338749-85-2) is a high-purity analytical reference standard with the molecular formula C13H5Cl2F3N2 and a molecular weight of 317.09 g/mol.
The molecular framework of 2-Chloro-6-(3-chlorophenyl)-4-(trifluoromethyl)pyridine-3-carbonitrile (C13H5Cl2F3N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
As a certified reference material (CRM), 2-Chloro-6-(3-chlorophenyl)-4-(trifluoromethyl)pyridine-3-carbonitrile 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.
