Chemical Structure
Description
The occurrence of 2,3,5,6-Tetrachloro-4-phenylpyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3,5,6-Tetrachloro-4-phenylpyridine (CAS 23985-88-8), a certified reference material (molecular formula C11H5Cl4N, MW 292.98 g/mol) for analytical method development and quality control.
The molecular framework of 2,3,5,6-Tetrachloro-4-phenylpyridine (C11H5Cl4N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,3,5,6-Tetrachloro-4-phenylpyridine 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.
