Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity organometallic reagents. Each batch is characterized by NMR (1H, 11B, 19F) and other analytical techniques to confirm identity and purity. Certificates of Analysis (COA) detailing assay, impurity profile, and moisture content are available upon request. We adhere to strict in-process controls to guarantee batch-to-batch consistency for your catalytic applications.

Storage

Preserve in a tightly closed container, protected from light. Store under a dry inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry, well-ventilated place. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed and handled under an inert atmosphere to prevent decomposition.
