Quality Control

Every batch of 2-Methyl-1-Propenylmagnesium Bromide is manufactured and tested under stringent quality management protocols. We ensure product integrity through rigorous analytical controls, including titration to determine concentration and purity. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to guarantee consistency and meet the exacting standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this reagent must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as water, acids, and oxidizing agents.
