Quality Control

Every batch of our 3-Pentylmagnesium Bromide solution is manufactured and analyzed under stringent quality control protocols to ensure consistency and reliability for sensitive synthetic applications. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing key parameters such as molarity, titration assay, and impurity profile. Our quality management system is designed to meet the exacting standards required for cGMP and ISO-guided production environments.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and pyrophoric nature in ether, it must be kept away from moisture, strong acids, and oxidizing agents. Recommended storage temperature is 2-8°C (under refrigeration) to maintain optimal stability and concentration. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
