Quality Control

Our (E)-3-Methyl-3-Nonene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high chemical and isomeric purity. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
