Quality Control

Our Ethylmagnesium Bromide is produced under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as concentration, assay, and impurity profiles. Our quality management system adheres to cGMP principles where applicable, supporting our commitment to supply reliability for critical B2B applications.

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. Due to its highly volatile and pyrophoric nature in concentrated solutions, it must be handled and stored away from heat, sparks, open flames, and oxidizing agents. Typically supplied and stored as a solution in diethyl ether or THF.
