Quality Control

Every batch of our Rel-Bis[(1R*)-2β*-(1,1-Dimethylethyl)-3,3-Dimethylcyclopropane-1α*-Yl] Zinc is manufactured and handled under strict inert atmosphere conditions to ensure integrity. We employ advanced analytical techniques, including NMR and titration, to verify identity, purity, and solution concentration. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is strictly light-sensitive and must be protected from all light exposure. It is also hygroscopic (moisture-sensitive) and easily oxidized; therefore, it must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for prolonged stability. Keep away from heat and incompatible materials such as strong acids and oxidizing agents.
