Quality Control

Our Lithium Triisopropyl 2-Thiophenylborate 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. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place (recommended 2-8°C) under an inert atmosphere (argon or nitrogen) due to its hygroscopic and easily oxidized nature. Allow the sealed container to reach ambient temperature before opening to minimize moisture ingress.
