Quality Control

Our sec-Butylmagnesium Bromide is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. The product undergoes rigorous analysis, including titration for concentration and purity assessment. A Certificate of Analysis (COA) detailing specific results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Due to its highly volatile and moisture-sensitive nature, the reagent is typically supplied and stored in sealed, septum-capped bottles or cylinders. Keep away from heat, sparks, open flames, and incompatible materials such as water, acids, and oxidizing agents.
