Quality Control

Our (E)-3,8-Nonadien-2-One is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent odor profile, and precise chemical identity. Certificates of Analysis (COA) detailing purity, isomer content, and physical properties are provided with every shipment to guarantee compliance with your specifications.

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). Keep away from heat, sparks, and open flame. This material is light-sensitive (store away from light) and may be susceptible to oxidation; optimal stability is maintained under an inert atmosphere for long-term storage.
