3-Bromo-4-fluorophenylboronic Acid (CAS 1092533-91-9): A Versatile Boronic Acid Derivative for Cross-Coupling Reactions

3-Bromo-4-fluorophenylboronic Acid (CAS 1092533-91-9) is an important boronic acid derivative widely used in pharmaceutical research, material science, and organic synthesis. This compound belongs to the class of arylboronic acids, which are crucial intermediates in Suzuki-Miyaura cross-coupling reactions – one of the most powerful methods for carbon-carbon bond formation in modern organic chemistry.

The molecular structure of 3-Bromo-4-fluorophenylboronic Acid features both bromine and fluorine substituents on the aromatic ring, making it particularly valuable for creating complex molecular architectures. The presence of these halogen atoms allows for further functionalization through various organic transformations, while the boronic acid group (-B(OH)₂) serves as the key reactive site for cross-coupling reactions.

In recent years, the demand for 3-Bromo-4-fluorophenylboronic Acid has increased significantly due to its applications in developing pharmaceutical intermediates and biologically active compounds. Researchers frequently search for information about its synthetic applications, handling precautions, and storage conditions, reflecting the growing interest in this compound within the scientific community.

From a chemical properties perspective, 3-Bromo-4-fluorophenylboronic Acid typically appears as a white to off-white crystalline powder. It exhibits moderate solubility in common organic solvents such as dimethyl sulfoxide (DMSO), tetrahydrofuran (THF), and dichloromethane, but has limited solubility in water. The compound is stable under inert atmospheres but may undergo protodeboronation under certain conditions, which is a common consideration when working with arylboronic acids.

The synthetic utility of 3-Bromo-4-fluorophenylboronic Acid (CAS 1092533-91-9) primarily lies in its role as a building block for Suzuki coupling reactions. This palladium-catalyzed process enables the formation of biaryl structures, which are prevalent in many drug molecules and functional materials. The simultaneous presence of bromine and fluorine substituents makes this compound particularly valuable for creating polyfunctionalized aromatic systems with precise control over substitution patterns.

Recent trends in medicinal chemistry have driven increased interest in fluorinated pharmaceuticals, making 3-Bromo-4-fluorophenylboronic Acid an important intermediate. Approximately 20-25% of all pharmaceuticals contain fluorine atoms, and this compound serves as a valuable precursor for developing new fluorinated drug candidates. Common search queries related to this application include "fluorinated boronic acids in drug discovery" and "Suzuki coupling with bromo-fluoro substrates".
