Quality Control

Every batch of our (1,3-Dimesitylimidazol-2-Ylidene)Nickel(0) Bis(Di-tert-Butyl Fumarate) is synthesized and handled under strict inert atmosphere conditions to preserve its catalytic activity. The product undergoes rigorous analytical characterization to ensure high purity and consistent performance. Comprehensive Certificates of Analysis (COA) detailing assay, identity, and impurity profiles are provided to support your quality assurance and regulatory compliance 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 dry, cold environment. This compound is both easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive). Allow the sealed container to reach ambient temperature before opening to minimize moisture condensation. Use immediately after opening under an inert atmosphere.
