Quality Control

Our Cyclopentylmagnesium Chloride is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including titration for assay determination and impurity profiling, to ensure consistency and high performance in your synthetic applications. Certificates of Analysis (COA) detailing concentration, purity, and solvent information are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and reacts violently with water. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from incompatible materials such as acids, alcohols, and oxidizers. For solutions, refer to the specific solvent's flammability and storage guidelines.
