Quality Control

Our 12-Methyl-2,5,8,11-Tetraoxatridecane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC and impurity profiling, to ensure it meets the high standards required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere (e.g., nitrogen blanket) to minimize potential oxidation.
