Cas no 942069-71-8 (3,4-Dichloro-5-methylphenylphenylboronic acid, pinacol ester)
3,4-Dichloro-5-methylphenylphenylboronic acid pinacol ester is a boronic ester derivative widely used as a key intermediate in Suzuki-Miyaura cross-coupling reactions. Its pinacol ester group enhances stability, improving handling and storage compared to free boronic acids. The compound’s aromatic dichloro and methyl substituents contribute to its utility in constructing complex heterocycles and functionalized biaryl structures, particularly in pharmaceutical and agrochemical synthesis. The steric and electronic properties of the substituents influence reactivity, allowing selective coupling under mild conditions. This reagent is valued for its consistent performance, high purity, and compatibility with diverse catalytic systems, making it a reliable choice for precision organic synthesis.
