3-Carboxyphenylboronic Acid丨CAS 25487-66-5

3-Carboxyphenylboronic acid is an important organoboron compound widely used as a building block in organic synthesis, pharmaceutical research, and materials science. It serves as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the construction of biaryl structures, heterocycles, and functionalized aromatic compounds. In medicinal chemistry, it is applied in the synthesis of enzyme inhibitors, anticancer agents, and boron-containing drugs. The carboxyl group provides additional reactivity, allowing conjugation to peptides, polymers, or biomolecules for targeted delivery and functionalization. Additionally, it is used in the development of sensors, materials for boron-based polymers, and chemical probes in biochemical research.

The benefits of 3-Carboxyphenylboronic acid stem from its dual functional groups-a boronic acid moiety and a carboxyl group-which provide high reactivity and versatility in chemical synthesis. The boronic acid enables efficient cross-coupling reactions, while the carboxyl group facilitates further derivatization and conjugation. This makes it valuable for creating complex molecules with high precision and yield. Its stability and high purity improve reproducibility in both laboratory and industrial applications. By offering chemical flexibility, it supports innovation in drug discovery, material development, and biochemical research.
