Used as a key intermediate in organic synthesis, particularly in the preparation of boron-containing conjugated materials for optoelectronic applications. It serves as a building block in the development of organic light-emitting diodes (OLEDs) and sensors due to its electron-deficient boron center and stable arylborane structure. The compound is also employed in Suzuki-Miyaura cross-coupling reactions to construct complex aromatic systems. Its steric bulk from mesityl groups enhances stability and influences regioselectivity in catalytic reactions. Additionally, it finds use in the study of charge-transfer complexes and luminescent materials.
