Quality Control

Our 4-Methylbenzylmagnesium Chloride is produced under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. The product undergoes rigorous analytical testing, including titration for assay determination and impurity profiling. Certificates of Analysis (COA) detailing purity, concentration, and solvent information are available for every batch upon request, supporting compliance with internal and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the reagent must be handled and stored under strictly anhydrous conditions to prevent decomposition. Recommended storage temperature is 2-8°C for extended stability.
