Quality Control

Our 2,8-Dimethyl-1,8-Nonadiene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and oxidizing agents. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature is 2-8°C.
