Quality Control

Our 3,6,7-Trimethyl-2,6-Octadienal is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent organoleptic quality suitable for demanding applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to keep the container under an inert gas blanket (e.g., nitrogen or argon) and minimize headspace after opening.
