As an accredited Octadecyltrichlorosilane factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 250 mL amber glass bottle with secure screw cap, clearly labeled "Octadecyltrichlorosilane" and hazard symbols, shipped in protective outer box. |
| Shipping | Octadecyltrichlorosilane should be shipped in tightly sealed containers under dry, inert conditions to prevent hydrolysis. It is classified as a hazardous material, requiring proper labeling and handling according to regulations. Avoid exposure to moisture and extreme temperatures. Shipping documentation should include safety data sheets and hazard classifications for safe transport. |
| Storage | Octadecyltrichlorosilane should be stored in a tightly sealed container, under a dry, inert atmosphere (such as nitrogen or argon) to prevent hydrolysis. Store in a cool, well-ventilated area away from moisture, water, and incompatible substances such as strong oxidizing agents. Protect from exposure to air and light. Handle using appropriate personal protective equipment to avoid inhalation or skin contact. |
