For professionals in chemical research and manufacturing, understanding the detailed properties and optimal applications of chemical intermediates is crucial for efficient workflow and successful project outcomes. Cyclopentylboronic Acid (CAS: 63076-51-7) is one such intermediate that plays a significant role in advanced organic synthesis. This guide aims to provide a thorough overview, covering its physical and chemical characteristics, its importance in various synthetic routes, and how to best approach purchasing it from reliable manufacturers.

Cyclopentylboronic Acid, with the chemical formula C5H11BO2 and a molecular weight of approximately 113.95, is characterized by its appearance as a white to off-white crystalline powder or flakes. It has a melting point of 126°C (with decomposition) and a flash point of 95.9°C. The density is typically around 1.03 g/cm³. Its high purity, often exceeding 97%, makes it a preferred choice for demanding chemical reactions where impurity levels can significantly impact the final product or reaction yield. When considering a purchase, always verify the purity and obtain detailed technical specifications.

The primary utility of Cyclopentylboronic Acid lies in its role as a versatile building block in organic chemistry. It is extensively employed in palladium-catalyzed cross-coupling reactions, such as the highly impactful Suzuki-Miyaura coupling. This reaction is a cornerstone for constructing complex carbon-carbon bonds, essential for the synthesis of pharmaceuticals, agrochemicals, and advanced materials. The ability to easily introduce a cyclopentyl moiety into a target molecule via this route makes Cyclopentylboronic Acid an indispensable reagent.
