Quality Control

We maintain stringent quality control protocols for our flavor and fragrance ingredients. Each batch of 2,6-Decadienal, 3,7,9-Trimethyl- is analyzed to ensure it meets exacting standards for identity, purity, and olfactory profile. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, isomer content, and sensory evaluation is provided with every shipment to guarantee consistency and reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled 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 of quality. Keep away from heat, sparks, and open flames.
