Quality Control

Our 4-n-Butylphenylmagnesium Bromide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm concentration, purity, and suitability for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing assay (typically by titration), solvent content, and other critical parameters is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and reacts violently with water and protic solvents. For optimal stability and safety, store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and oxidizing agents.
