2-Bromomethylphenylboronic acid(CAS: 91983-14-1)

2-Bromomethylphenylboronic acid is a crystalline solid with a molecular weight of approximately 242.04 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and dimethylformamide. The compound is highly reactive, especially under basic conditions. It is often used in Suzuki cross-coupling reactions due to its boronic acid functionality.

2-Bromomethylphenylboronic acid is typically synthesized by reacting 2-methylphenylboronic acid with hydrobromic acid in the presence of a base like potassium carbonate. The reaction is highly selective and yields a high purity product with good yield. The key steps involve protecting the phenolic hydroxyl group, bromination, and then the boronation step.

2-Bromomethylphenylboronic acid is widely used in the pharmaceutical industry for the synthesis of drug intermediates, particularly in Suzuki cross-coupling reactions. It also finds applications in the polymer industry for the preparation of functional polymers and in the semiconductor industry for the fabrication of electronic materials.

When handling 2-Bromomethylphenylboronic acid, it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The compound should be handled in a fume hood to minimize inhalation risks. Spills should be cleaned up with appropriate absorbent materials and disposed of according to local regulations. It is advisable to consult the Safety Data Sheet (SDS) for detailed safety information.
