Quality Control

Our 3,7-Dichloro-5,5-Dimethyl-5H-Dibenzo[B,F]Silepine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency suitable for demanding R&D and scale-up processes. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials.
