Quality Control

Our production of 7,8,12,13-Tetrakis[(Trimethylsilyl)Oxy]Octadecanoic Acid Methyl Ester adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and industrial use. All materials are characterized using advanced analytical techniques, including NMR, HPLC, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

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) after opening to prevent degradation. Keep away from heat and incompatible materials.
