Quality Control

Our 1,2-Binaphthyl-4-Ylboronic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C to minimize decomposition and oxidation.
