Quality Control

Every batch of (3Z)-9-Methyl-3-Undecene is produced and tested under a strict quality management system. We ensure high purity and consistent isomeric composition through advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific R&D or production requirements.

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 area, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and only opened in a controlled environment. Recommended storage temperature is 2-8°C for long-term stability.
