2-bromo-5-chloro-1,1-biphenyl丨CAS 1936711-65-7

2-Bromo-5-chloro-1,1-biphenyl is a halogenated aromatic intermediate widely used in organic synthesis and pharmaceutical research. It is primarily employed as a building block in the synthesis of biaryl compounds, which are important motifs in pharmaceuticals, agrochemicals, and advanced materials. Its bromine and chlorine substituents provide reactive sites for selective cross-coupling reactions, such as Suzuki, Negishi, and Stille couplings, enabling the construction of complex polyaryl frameworks. Additionally, it is used in medicinal chemistry for developing drug candidates, functionalized ligands, and heterocyclic derivatives, as well as in material science for designing organic semiconductors, polymers, and specialty chemicals.

The benefits of 2-bromo-5-chloro-1,1-biphenyl are derived from its dual halogen functionality, structural rigidity, and chemical stability. The presence of both bromine and chlorine allows for regioselective functionalization and high-efficiency cross-coupling reactions, facilitating the synthesis of structurally diverse and complex molecules. Its biphenyl core provides planarity and rigidity, which are valuable properties for pharmaceuticals, ligands, and material applications. Additionally, it is compatible with a variety of reaction conditions, scalable for industrial use, and supports reproducible results in both laboratory and commercial synthesis. These characteristics make it a reliable and versatile intermediate for complex organic transformations.
