Trimethoxy(octadecyl)silane(CAS: 3069-42-9)

Trimethoxy(octadecyl)silane (CAS: 3069-42-9) is a colorless, viscous liquid with the chemical formula C23H50O3Si. It features a silane backbone with three methoxy groups and an octadecyl chain, making it a versatile coupling agent. This compound is commonly used for surface modification and exhibits low reactivity under normal conditions, with a molecular weight of approximately 400 g/mol.

Trimethoxy(octadecyl)silane (CAS: 3069-42-9) is primarily used as a coupling agent in pharmaceuticals, coatings, and materials science. It facilitates the creation of silane-based coatings, enhances adhesion in composite materials, and is applied in research for functionalizing surfaces. Its octadecyl group also makes it suitable for hydrophobic modification in industrial applications.

Trimethoxy(octadecyl)silane (CAS: 3069-42-9) is generally considered safe when handled properly, but it requires standard chemical safety precautions. Toxicity data indicates low acute toxicity, though prolonged skin contact or inhalation may cause irritation. Always use gloves, ensure adequate ventilation, and follow OSHA guidelines for safe handling and disposal.

Trimethoxy(octadecyl)silane (CAS: 3069-42-9) should be stored in a cool, dry place, away from light and moisture. Keep in tightly sealed containers at temperatures below 25°C to maintain stability. Avoid exposure to heat sources and store in a well-ventilated area to prevent potential evaporation or contamination.
