Quality Control

Our 3,4,4A,5,6,7,8,8A-Octahydro-2,5,5,8A-Tetramethylnaphthalene-1-Acetaldehyde is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent olfactory profile, and batch-to-batch reliability essential for fragrance applications. Certificates of Analysis (COA) detailing identity, purity, and specific impurity limits are available upon request.

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). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and prevent degradation. Keep away from heat, sparks, and open flame.
