Quality Control

Our 4-n-Pentylphenylmagnesium Bromide is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm concentration (typically supplied as a solution in THF or diethyl ether), purity, and freedom from deleterious impurities. A comprehensive Certificate of Analysis (COA) detailing assay results, titration data, and solvent content is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored under an inert atmosphere (argon or nitrogen) to prevent decomposition. For solutions, store at 2-8°C in a cool, dry, well-ventilated area away from incompatible materials such as acids, oxidizers, and moisture. Keep the container tightly sealed when not in use.
