Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for high-purity organometallic reagents. Each batch is controlled via advanced analytical techniques to guarantee identity, purity, and reactivity. Certificates of Analysis (COA) detailing lot-specific results are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an 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 sealed and allowed to reach room temperature before opening to minimize moisture ingress and decomposition.
