Quality Control

Our 9-Methyl-1-Undecene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability.
