Quality Control

Our production of 2-Ethylhexyl 10-Ethyl-4,4-Bis[3-(Octadecyloxy)-3-Oxopropyl]-7-Oxo-8-Oxa-3,5-Dithia-4-Stannatetradecanoate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay (HPLC), identification (IR, NMR), and impurity profiling, to ensure consistency and compliance with industry specifications. Certificates of Analysis (COA) documenting purity, physical properties, and heavy metal content are available upon request to support your quality assurance and regulatory needs.

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 each use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
