Quality Control

Our Butyryl Bromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, IR, and titration methods, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your precise application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. Due to its hygroscopic and strong acid/organic solvent nature, it must be kept away from moisture, bases, and oxidizing agents. Use appropriate corrosion-resistant storage materials.
