Description

Bis(4-methylphenyl)borinic acid (CAS No. 66117-64-4) is an organoboron compound with the molecular formula C₁₄H₁₅BO. This high-purity reagent is widely used in organic synthesis, catalysis, and materials science due to its unique boron-centered Lewis acidity and stability. The compound features two para-methylphenyl groups attached to a borinic acid moiety, making it a versatile intermediate for cross-coupling reactions, polymerization catalysts, and ligand design. Available in crystalline or powder form, our product is rigorously tested for purity (typically ≥95% by HPLC or NMR) and is packaged under inert conditions to ensure long-term stability. Ideal for researchers developing novel boron-containing polymers, pharmaceuticals, or optoelectronic materials.
