Quality Control

Our Lithium Triisopropyl 2-(5-Methoxypyridyl)Borate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical 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. This product is hygroscopic (moisture-sensitive) and must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
