Quality Control

Every batch of 2,7-Dimethyl-5-(1-methylethenyl)-1,8-nonadiene is produced and tested under a strict quality management system. We ensure high purity and consistent isomeric composition through advanced analytical techniques including GC, GC-MS, and NMR. 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 under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flames. For long-term stability, minimize headspace in opened containers.
