Quality Control

Our Ethyl 2-trans-4-cis-Decadienoate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for flavor, fragrance, and food applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with every shipment. We adhere to relevant industry guidelines, including FEMA and FCC where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
