Quality Control

Our 1,3-Heptadiyne is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for reliable supply to regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably at 2-8°C (refrigerated) or as specified on the label. Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed when not in use to prevent evaporation and potential concentration of peroxides.
