Quality Control

Our 4-n-Propylphenylmagnesium Bromide is manufactured under stringent quality systems. Each batch undergoes rigorous analytical testing, including titration for Grignard concentration and GC/HPLC analysis for solvent purity and by-products, to ensure consistency and reactivity. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee compliance with your research and process requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and highly volatile. For optimal stability and safety, store under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
