Quality Control

Our 2-Bromo-1-Butene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC and NMR analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent degradation and maintain purity. Recommended storage temperature is 2-8°C.
