Description

3-(Cyclopentylaminocarbonyl)Phenylboronic Acid, Neopentyl Glycol Ester is a specialized organoboron compound where the boronic acid moiety is protected as a neopentyl glycol ester. This chemical structure is significant as it provides enhanced stability and handling properties compared to the free boronic acid, making it a valuable intermediate in advanced synthetic chemistry. It is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for applications in cross-coupling reactions, such as the Suzuki-Miyaura reaction, to construct complex molecular architectures.

Application

• Key intermediate in Suzuki-Miyaura cross-coupling reactions for C-C bond formation in pharmaceutical research.
• Building block for the synthesis of active pharmaceutical ingredients (APIs) and drug candidates.
• Precursor in the development of agrochemicals, including herbicides and fungicides.
• Used in material science for creating organic electronic materials and polymers.
• Intermediate in chemical biology for probe and sensor development.
• Research chemical for methodology development in organometallic and catalytic chemistry.

Quality Control

Our 3-(Cyclopentylaminocarbonyl)Phenylboronic Acid, Neopentyl Glycol Ester undergoes rigorous quality testing to ensure compliance with industry standards for research and development use. Each batch is analyzed to confirm identity, purity, and stability. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
