Quality Control

Our technical-grade 5,7-Dimethyl-3,5,9-decatrien-2-one is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by GC or HPLC, to ensure it meets the specified purity of approximately 85% and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and support your quality assurance protocols.

Storage

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