Quality Control

Our 4-(3,3-Dimethylbicyclo[2.2.1]Hept-2-Yl)-2-Ethyl-2-Butenal is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity, consistent olfactory profile, and batch-to-batch reliability. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request. We adhere to relevant industry standards for fragrance and flavor ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from strong oxidizing agents, strong acids, and strong bases. This material is light-sensitive; prolonged exposure to light should be avoided to maintain stability and organoleptic properties.
