Quality Control

Every batch of 2-Trimethylsiloxy-4-Allyloxydiphenylketone is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for high-purity intermediates. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistency for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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. Keep away from incompatible materials.
