Quality Control

Our trans-Bis(Triethylphosphine)(2,4,6-Trimethylphenyl)Nickel(II) Bromide is manufactured under controlled conditions and undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Each lot is analyzed to confirm identity, purity, and absence of critical metallic impurities. Certificates of Analysis (COA) detailing specific test results are available upon request.

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 place. This material is hygroscopic (moisture-sensitive) and easily oxidized; exposure to air and moisture must be minimized to preserve stability and catalytic activity.
