Product Description:

2,3-Difluorophenylboronic acid is an organoboron compound featuring a phenyl ring substituted with two fluorine atoms at the ortho and meta positions and a boronic acid functional group. It is a white to off-white crystalline powder and serves as a versatile synthetic building block, particularly in Suzuki-Miyaura cross-coupling reactions for constructing biaryl structures. Its primary industrial significance lies in the field of advanced materials. It is a key intermediate in the synthesis of various organic electronic materials, including charge-transporting materials, host materials, and emitters for organic light-emitting diodes (OLEDs). The introduction of fluorine atoms is a common strategy to fine-tune the electronic properties, thermal stability, and molecular packing of these materials, which are crucial for device performance in displays and lighting. As a boronic acid derivative, it requires careful handling under inert conditions (e.g., nitrogen or argon) to prevent protodeboronation and maintain stability. It is commercially available from major chemical suppliers for research and development in organic synthesis and materials science.
