CAS Number: 87547-04-4
Cyclopropylboronic Acid Pinacol Ester is a versatile organoboron reagent used in palladium-catalysed Suzuki-Miyaura cross-coupling reactions for the introduction of a cyclopropyl group into complex organic molecules. In construction chemistry, cyclopropyl-containing compounds are intermediates in the synthesis of speciality monomers for high-performance polymer coatings and adhesive systems. AB Enterprises supplies this compound to manufacturers and researchers requiring a stable, air-tolerant boronic ester building block. The pinacol ester protection enhances stability relative to the free boronic acid, facilitating storage and handling in standard laboratory conditions. It is also used in the preparation of novel epoxy and polyurethane monomers with enhanced mechanical properties for construction applications.
