Quality Control

Our 5-Bromo-2-pentene is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and impurity profiling, to meet the stringent requirements of research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent evaporation and moisture ingress.
