Quality Control

Our production of 12,12-Bis[2-[2-(2-Methoxyethoxy)Ethoxy]Ethoxy]-2,5,8,11,13,16,19,22-Octaoxa-12-Silatricosane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to confirm identity, purity, and moisture content. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and compliance with your technical requirements.

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 degradation from atmospheric moisture. For long-term storage, consider using an inert atmosphere or desiccant.
