Quality Control

Our 1,2-Di(Prop-2-Enyl)-Tetramethyldisilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Comprehensive Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided to guarantee compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, containers must be kept tightly sealed and away from heat sources and open flame. Use under an inert atmosphere for extended storage to maintain product integrity.
