Quality Control

Our 3-Methylbenzylmagnesium Chloride is produced under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. We adhere to relevant industry standards for organometallic reagents. A comprehensive Certificate of Analysis (COA) detailing assay, concentration, and impurity profiles is provided with every shipment to guarantee product integrity and traceability.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive nature, this product is typically supplied and stored as a solution in an appropriate ether solvent (e.g., THF, diethyl ether) under an inert atmosphere (argon or nitrogen) to prevent oxidation and hydrolysis. Store in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Keep the container tightly sealed under a positive pressure of inert gas. Recommended storage temperature is 2-8°C for extended stability.
