Quality Control

Our Butylmagnesium Chloride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Production adheres to cGMP principles where applicable, and each lot is accompanied by a comprehensive Certificate of Analysis (COA). The COA provides detailed results for key parameters including assay (by titration), concentration in solution, and impurity profiles, ensuring the material meets the rigorous demands of synthesis and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and pyrophoric nature in certain concentrations, it is typically supplied and stored as a solution in specific ether solvents like THF or diethyl ether. Follow all relevant safety data sheet (SDS) instructions for handling.
