Quality Control

Our (3E)-3,7-Dimethylocta-1,3,6-Triene is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis including assay, isomer purity, and impurity profiling to ensure it meets exacting standards for fragrance, flavor, and synthetic applications. Certificates of Analysis (COA) detailing specifications such as purity (typically >95% by GC), identity, and residual solvents are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent evaporation and potential oxidation.
