Description
CATO supplies 2-(3,5-Dichlorophenyl)pyridine (CAS 1379370-04-3), a certified reference material (molecular formula C11H7Cl2N, MW 224.09 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H7Cl2N, 2-(3,5-Dichlorophenyl)pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 224.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
