Quality Control

Our 4-(Cyclopentyl)Aminomethyl Phenylboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and consistent performance for sensitive synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to maintain stability and prevent hydrolysis. Keep container tightly sealed in a desiccated environment.
