Quality Control

Our 3,7,11-Trimethyl-1-Dodecene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) and other relevant methods, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming the product meets agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, although short-term storage at 15-25°C is acceptable.
