Quality Control

Our Undecylenicaldehydedigeranylacetal is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity, consistent odor profile, and chemical identity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. Our quality commitment aligns with the standards expected by the fragrance and fine chemical industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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) for long-term preservation. Keep away from heat, sparks, and open flames.
