Quality Control

Our 6-(Cyclopentylamino)Pyridine-2-Boronic Acid Pinacol Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR (1H, 13C, 11B), and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with full analytical data are provided for each lot to support your R&D and regulatory requirements.

Storage

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