Quality Control

Our 1,6-Heptadiene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at temperatures between 2°C and 8°C (35°F and 46°F) to minimize evaporation and maintain stability. Keep away from heat, sparks, and open flames. For long-term storage, consider using under an inert atmosphere such as nitrogen to prevent potential oxidation.
