Application

(2-Aminophenyl)boronic acid is widely used as a key reagent in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. It serves as a precursor for synthesizing boron-containing pharmaceuticals and agrochemicals. The ortho-aminophenyl group enhances its utility in designing fluorescent probes and sensors for diol recognition. Researchers also employ it in metal-organic framework (MOF) functionalization and as a ligand in transition-metal catalysis.
