Chemical Structure
Description
As a certified reference material (CRM), 5-(chloromethyl)pyridine-3-carbonitrile;hydrochloride 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.
5-(chloromethyl)pyridine-3-carbonitrile;hydrochloride (CAS 189936-27-4) is a high-purity analytical reference standard with the molecular formula C7H11ClN2HCl and a molecular weight of 195.09 g/mol.
The molecular framework of 5-(chloromethyl)pyridine-3-carbonitrile;hydrochloride (C7H11ClN2HCl) is characterized by a nitrile group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
