Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-1-methylpyridinium Iodide 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.
CATO supplies 2-Chloro-1-methylpyridinium Iodide (CAS 14338-32-0), a certified reference material (molecular formula C6H7ClNI, MW 255.48 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-1-methylpyridinium Iodide (C6H7ClNI) is characterized by a nitrile group, chlorine/iodine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
