Description

Boronic Acid, [4'-(Diphenylamino)[1,1'-Biphenyl]-4-Yl]- is a high-purity, functionalized boronic acid derivative characterized by its extended biphenyl system with a central diphenylamino donor group. This compound is a critical advanced organic intermediate valued for its role in cross-coupling reactions, particularly the Suzuki-Miyaura reaction, enabling the synthesis of complex molecular architectures. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and organic electronics sectors who require precise building blocks for drug discovery, material science, and specialty chemical synthesis.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, especially those requiring complex biaryl structures.
• Organic Light-Emitting Diode (OLED) Materials: Serves as a precursor for electron-transporting or host materials in OLED displays and lighting due to its conjugated, electron-rich aromatic system.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that incorporate advanced aromatic amine motifs.
• Cross-Coupling Reactions: Primarily employed as a boronic acid coupling partner in Suzuki-Miyaura reactions to form carbon-carbon bonds under mild conditions.
• Material Science Research: Utilized in the development of organic semiconductors, conductive polymers, and other functional organic materials.
• Chemical Biology & Sensing: Acts as a versatile handle for bioconjugation or as a component in the design of molecular sensors and probes.
