Quality Control

Our Cyclopropylmethyl Magnesium Bromide is produced and handled under stringent quality systems. Each batch undergoes rigorous analytical testing, including titration for assay and GC analysis for solvent and impurity profiles, to ensure consistency and high reactivity. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this reagent 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 water.
