Quality Control

Our (Z)-1-Bromo-1-Pentene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and chiral analysis, to confirm identity, purity, and stereochemical integrity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 and light-sensitive nature, containers should be kept tightly sealed and away from heat, sparks, and open flame. Use under an inert atmosphere for extended storage to maintain optimal purity.
