Quality Control

Our Ethyl 6-Heptynoate, 97% is manufactured under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to verify identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 2°C and 8°C for extended stability, although the product is stable at controlled room temperature for shorter periods. Keep container tightly sealed when not in use to minimize moisture absorption and prevent evaporation.
