Quality Control

Our (E)-Undec-4-Ene is produced and handled under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to verify identity, isomeric purity, and chemical composition. A Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and contamination.
