Quality Control

Every batch of our Chloro(Cyclopentadienyl){1,3-Bis[2-(Diphenylmethyl)-4,6-Dimethylphenyl]1H-Imidazolium}Nickel(II) is synthesized and handled under strict inert atmosphere conditions to ensure integrity. Our products undergo rigorous quality testing, including NMR (1H, 13C) and Elemental Analysis (CHN), to verify identity and purity, ensuring compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

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, freezer-safe environment. This compound is moisture-sensitive (hygroscopic) and easily oxidized; prolonged exposure to air, light, or ambient temperature will degrade the product.
