Chemical Structure
Description
4,5'-Dimethyl-2,2'-bipyridine (CAS 282541-27-9) is a high-purity analytical reference standard with the molecular formula C12H12N2 and a molecular weight of 184.24 g/mol.
The molecular framework of 4,5'-Dimethyl-2,2'-bipyridine (C12H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4,5'-Dimethyl-2,2'-bipyridine 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.
