Quality Control

Our (E)-3,3-Dimethyl-1,5-Heptadiene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high chemical purity and isomeric integrity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flames. Due to its highly volatile nature, allow the container to reach ambient temperature before opening to prevent moisture ingress and pressure buildup.
