Quality Control

Our (2E,6E)-2,6-Octadienal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 stability. Keep away from heat, sparks, and open flames.
