For research scientists and chemists working at the forefront of materials science and organic synthesis, a thorough understanding of chemical properties is paramount. 4-Bromo-4'-tert-butylbiphenyl, identified by its CAS number 162258-89-1, is a compound whose specific attributes make it invaluable in various advanced applications. Knowledge of its physical and chemical characteristics aids in its effective utilization and procurement from reliable manufacturers.

The molecular formula C16H17Br and a molecular weight of approximately 289.21 g/cm³ define the basic composition of this biphenyl derivative. Visually, it is typically presented as a white powder, a common characteristic for many organic intermediates. Its melting point, reported at 143°C, is a key indicator of its solid-state stability and purity, and is crucial data for formulators and process engineers.

Further insights into its physical properties include a boiling point of 152°C/2mm, suggesting its stability under vacuum distillation, a common purification technique. The density is noted as 1.217±0.06 g/cm³, which is relevant for volumetric calculations in manufacturing and research. Its flash point (Fp) at 152°C/2mm also provides an indication of its flammability profile, which is important for safe handling and storage procedures.

Chemically, the presence of the bromine atom on one phenyl ring and the tert-butyl group on the other makes 4-Bromo-4'-tert-butylbiphenyl a versatile synthetic intermediate. The bromine atom is highly reactive in palladium-catalyzed cross-coupling reactions, facilitating the formation of new carbon-carbon bonds. This reactivity underpins its use in creating complex organic structures for advanced materials.

Solubility is another critical property; this compound exhibits transparency in Toluene, indicating good solubility in many organic solvents. This makes it amenable to various solution-based synthesis and processing methods. For effective storage, manufacturers recommend maintaining the compound at temperatures between +5°C and +30°C, ensuring its longevity and integrity.

When seeking to buy 4-Bromo-4'-tert-butylbiphenyl, researchers should look for suppliers that clearly list these properties and guarantee a minimum purity of 97%. Understanding these technical specifications allows scientists to confidently incorporate this chemical into their experiments and production processes, knowing they are using a high-quality product. Sourcing from reputable China manufacturers often provides access to this critical information and ensures a reliable supply chain.
