Quality Control

Our high-purity catalyst is manufactured under controlled conditions to ensure batch-to-batch consistency and optimal catalytic performance. Each lot undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to verify identity, purity, and the absence of deleterious impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to maintain stability and prevent decomposition. This material is moisture-sensitive (hygroscopic) and easily oxidized; ensure containers are sealed immediately after use and handled in a dry, inert environment.
