Quality Control

Our 2-Ethylphenylmagnesium Bromide is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Quality is assured through rigorous in-process controls and final testing, including titration for concentration and analysis of reactive impurities. A comprehensive Certificate of Analysis (COA) detailing concentration, solvent, and purity is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive nature, this product 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 strong acids, oxidizers, and protic solvents.
