As an accredited Octyltrichlorosilane factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Octyltrichlorosilane, 100 mL, is supplied in a sealed amber glass bottle with a Teflon-lined cap for moisture protection. |
| Shipping | Octyltrichlorosilane should be shipped in tightly sealed containers under a dry, inert atmosphere to prevent hydrolysis, as it reacts with moisture. It is classified as a hazardous material (UN 2987), requiring packaging that meets regulatory standards for corrosive liquids. Proper labeling and documentation are essential during transportation. Store separately from incompatible substances. |
| Storage | Octyltrichlorosilane should be stored in a tightly sealed container, in a cool, dry, and well-ventilated area, away from moisture, heat, and sources of ignition. Store under inert atmosphere such as nitrogen. Avoid contact with water, alcohols, and acids, as it reacts violently, releasing corrosive hydrogen chloride gas. Use compatible containers, typically glass or certain plastics, to prevent decomposition. |
