Quality Control

Our 2-Butyl-2-Ethyl-5,7-Dimethyl-3,4-Octadienal is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent composition suitable for demanding applications in flavor, fragrance, and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
