Quality Control

Our 3,3,6-Trimethyl-1,4-Heptadiene is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature: 2-8°C (refrigerated) for extended stability, or at controlled room temperature for short-term use.
