Chemical Structure
Description
The occurrence of 2-Chloro-3-(5-fluoro-2-methylbenzenesulfonyl)-4,6-dimethylpyridine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Chloro-3-(5-fluoro-2-methylbenzenesulfonyl)-4,6-dimethylpyridine (CAS 339276-96-9), a certified reference material (molecular formula C14H13ClFNO2S, MW 313.77 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H13ClFNO2S, 2-Chloro-3-(5-fluoro-2-methylbenzenesulfonyl)-4,6-dimethylpyridine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 313.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-3-(5-fluoro-2-methylbenzenesulfonyl)-4,6-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.
