Cas no 1218789-82-2 (3-Butoxy-5-methylphenylboronic acid, pinacol ester)

3-Butoxy-5-methylphenylboronic acid pinacol ester is a stable boronic ester derivative commonly employed in Suzuki-Miyaura cross-coupling reactions. The pinacol ester moiety enhances shelf stability and handling compared to the free boronic acid, reducing susceptibility to protodeboronation. The butoxy and methyl substituents influence reactivity and steric properties, making this compound useful in constructing complex aryl frameworks. Its compatibility with mild reaction conditions and broad functional group tolerance makes it a versatile intermediate in pharmaceutical and materials science applications. The product is typically supplied as a crystalline solid, ensuring consistent purity and performance in synthetic workflows.
