Quality Control

Our Bis(Trimethylsilyl) Vinylphosphonate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including purity assay and impurity profiling by GC and NMR. A Certificate of Analysis (COA) is supplied with each batch, detailing all relevant specifications to support your R&D and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability.
