In the intricate world of organic chemistry, understanding the synthesis pathways and properties of key intermediates is fundamental to scientific advancement and industrial production. 4-Bromo-p-terphenyl, identified by its CAS number 1762-84-1, is a compound of significant interest due to its utility in creating advanced materials, particularly for the electronics sector. NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical supplier, sheds light on the synthesis and properties of this crucial molecule.

The structure of 4-Bromo-p-terphenyl is a terphenyl unit – three phenyl rings linked together – with a bromine atom attached to one of the terminal phenyl rings. This specific arrangement imparts unique electronic and chemical properties. The terphenyl backbone provides rigidity and facilitates pi-electron delocalization, which is essential for charge transport and luminescent properties in organic electronic devices. The bromine atom serves as a reactive functional group, enabling facile derivatization through various organometallic coupling reactions, such as palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Stille).

The synthesis of 4-Bromo-p-terphenyl typically involves multi-step organic transformations. While specific industrial routes may vary, common approaches often start with readily available precursors and build the terphenyl structure through sequential coupling reactions. For instance, one might synthesize p-terphenyl first and then introduce the bromine atom via electrophilic aromatic substitution, or assemble the brominated terphenyl structure from smaller, functionalized aromatic units. The precision required in these synthetic routes is critical to achieving the high purity (u226599.0%) that is demanded for its applications.

Key properties of 4-Bromo-p-terphenyl include its appearance as a white powder. Its melting point is typically around 232u00b0C, indicating a stable solid form at room temperature. The molecular formula is C18H13Br, with a molecular weight of approximately 309.2 g/mol. These physical and chemical characteristics make it a manageable compound for handling and processing in laboratory and industrial settings. Proper storage in a cool, dry place, away from direct sunlight, is recommended to maintain its integrity.
