Quality Control

Our 1,5-Heptadiene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis using advanced techniques such as Gas Chromatography (GC) and NMR to verify identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (refrigerated) to minimize evaporation and maintain stability. Keep away from strong oxidizing agents.
