Quality Control

Our (E)-3,7-Dimethylocta-1,3,6-Triene is produced and tested under a strict quality management system. Every batch is analyzed using advanced chromatographic techniques (GC, GC-MS) to ensure identity, purity, and olfactory profile consistency. A comprehensive Certificate of Analysis (COA) detailing assay, isomer content, and physical properties is provided with each shipment. We can supply grades suitable for research, fragrance, and flavor applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, it is recommended to keep it under an inert atmosphere (e.g., nitrogen or argon) to maintain optimal quality and prevent degradation.
