Quality Control

Our production of [2-(3-Cyclohexenyl)Ethyl]Triethoxysilane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We are committed to meeting the quality standards required for industrial and research applications.

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/59-77°F). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from strong bases and incompatible materials.
