4-Biphenylboronic Acid CAS 5122-94-1

① Acts 4-Biphenylboronic acid as a key reagent for Suzuki-Miyaura cross-coupling reactions, enabling synthesis of biaryl pharmaceuticals, liquid crystals and OLED materials by coupling with aryl halides to build complex aromatic structures.

② Serves 4-Biphenylboronic acid CAS 5122-94-1 as a core intermediate for preparing functional organic dyes and pigments via boronic acid - mediated coupling to adjust chromophore structures and enhance color stability.

③ Functions as a building block for organic semiconductors and porous materials, supporting R&D of high - performance electronic components and adsorption materials with its rigid biphenyl - boronic acid structure.

Store 4-Biphenylboronic acid CAS 5122-94-1 at 2-8℃ in sealed amber glass/HDPE drums in a cool, dry, dark well-ventilated area, away from open fire, strong oxidants, strong bases and direct sunlight. Wear nitrile gloves, safety goggles and dust mask; avoid inhalation, skin/eye contact & ingestion to prevent mild irritation. Reseal tightly post-use to avoid moisture absorption, hydrolysis and dimerization to anhydride. Dispose via licensed hazardous waste channels; transport as non-hazardous solid, keep refrigerated, avoid high-temperature exposure and mixing with halides/strong bases.

4-Biphenylboronic acid CAS 5122-94-1 is a low - toxic white crystalline solid with excellent chemical stability, non - flammable, low hygroscopicity and no self - polymerization risk under proper storage. The boronic acid group offers high coupling reactivity; rigid biphenyl core ensures structural stability of target products, high purity guarantees high reaction yield and selectivity, good solubility in THF/DMF/ethanol, cost - effective for large - scale synthesis with stable batch quality and easy purification.
