    —— Product Detail ——




                    • Product Overview

                      4,4'-Dimethyl-2,2'-bipyridine is an organic compound with the molecular formula C₁₂H₁₂N₂ and molecular weight of 184.24 g/mol. This white to light yellow crystalline solid is a substituted bipyridine ligand, featuring methyl groups at the 4 and 4' positions of the bipyridine core. The methyl substituents provide both steric and electronic effects that can be tuned for specific catalytic applications.

                      Synthetic Process

                      4,4'-Dimethyl-2,2'-bipyridine is synthesized through various routes:

                      • Coupling of Methylpyridine: 4-methylpyridine is coupled using Raney nickel or other catalysts to form 4,4'-dimethyl-2,2'-bipyridine

                      • Purification: The crude product is purified by recrystallization from appropriate solvents

                      • Quality Control: The final product is analyzed to ensure ≥98.0% purity

                      Mechanism of Action

                      • Metal Coordination: Acts as a bidentate ligand, coordinating to metals through both nitrogen atoms

                      • Electronic Tuning: The methyl groups provide electron-donating effects that modify the electronic properties of the metal center

                      • Catalysis: Metal complexes of this ligand are used in various catalytic transformations

                      • Photochemistry: Used in the preparation of photoluminescent metal complexes

                      Research Applications

                      • Coordination Chemistry: Substituted bipyridine ligand for transition metal complexes

                      • Catalysis: Ligand for catalytic systems including photoredox catalysis

                      • Electrochemistry: Used in preparation of electrochemical sensors

                      • Materials Science: Building block for functional materials

                      • Pharmaceutical Research: Used in the synthesis of metallodrug candidates

                      Quality Specifications

                      • Purity: ≥98.0% (GC)

                      • Melting point: 170-174°C

                      • Solubility: Soluble in organic solvents

                      • Storage: 2-8°C, sealed, protected from light

                      Packaging & Shipping

                      • Research quantities: 5g, 25g amber glass vials

                      • Bulk quantities: 100g, 500g amber glass bottles

                      • Shipped at ambient temperature
