Quality Control

Our Methyl 17-Methyloctadecanoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its easily oxidized nature, minimize headspace in opened containers and handle under inert conditions for long-term stability.
