Chemical Structure
Description
2-(2,5-Dichloroanilino)pyridine-3-carbonitrile (CAS 1019357-51-7) is a high-purity analytical reference standard with the molecular formula C12H7Cl2N3 and a molecular weight of 264.11 g/mol.
2-(2,5-Dichloroanilino)pyridine-3-carbonitrile (C12H7Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(2,5-Dichloroanilino)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.
