Understanding the precise chemical structure and inherent properties of a compound is fundamental for its effective application in research and industry. 4,4'-Dibromobipyridine (CAS 18511-71-2) is a heterocyclic organic compound that has gained significant attention due to its utility as a versatile building block in advanced synthesis. As a leading supplier of fine chemicals, we provide detailed insights into its characteristics that empower scientists and product developers.

The chemical formula for 4,4'-Dibromobipyridine is C10H6Br2N2, with a molecular weight of approximately 313.98 g/mol. Structurally, it consists of two pyridine rings linked at the 2 and 2' positions. Crucially, bromine atoms are attached to the carbon atoms at the 4 and 4' positions of these rings. This specific arrangement imbues the molecule with unique electronic properties. The pyridine rings themselves are electron-deficient, and the presence of the electronegative bromine atoms further enhances this characteristic, making it an excellent electron-withdrawing moiety.

Key physical properties often sought by researchers include its appearance, melting point, and solubility. 4,4'-Dibromobipyridine is typically supplied as a white to light yellow powder. Its melting point falls within the range of 138.0 to 142.0 °C, a parameter that signifies its purity and thermal stability. While soluble in certain organic solvents like toluene, its solubility in water is limited, which is typical for many organic intermediates.

The significance of these structural features and properties lies in its broad applicability. Scientists often search for '4,4'-dibromobipyridine properties' or 'CAS 18511-71-2 structure' to understand its reactivity and potential. Its electron-deficient nature and the reactive bromine atoms make it an ideal starting material for cross-coupling reactions (e.g., Suzuki, Sonogashira couplings), enabling the synthesis of more complex conjugated systems. These systems are vital for developing materials used in Organic Light-Emitting Diodes (OLEDs), organic photovoltaics (OPVs), and as ligands in organometallic catalysis.
