Chemical Structure
Description
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 2-Chloro-4,5-dimethylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2-Chloro-4,5-dimethylpyridine (CAS 343268-69-9), a certified reference material (molecular formula C7H8ClN, MW 141.60 g/mol) for analytical method development and quality control.
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.
CATO manufactures 2-Chloro-4,5-dimethylpyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
