Quality Control

Our 1,3-Dichloro-1,1,3,3-Tetraisopropyldisiloxane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee consistency and traceability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from incompatible materials such as strong bases, oxidizing agents, and moisture.
