Quality Control

Our 4,7,10,13,16-Pentaoxanonadeca-1,18-Diyne is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Our quality systems support development and production needs in compliance with cGMP and ISO standards where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture uptake and oxidation. Keep away from strong oxidizing agents.
