CAS 3069-40-7: Octiltrimetossisilano

1-(Trimethoxysilyl)octane is a glycol ether that is used as a solvent for organic and inorganic compounds. It can be used to clean radiation-sensitive surfaces, such as those found in the semiconductor industry. This compound has been shown to have a strong adsorption mechanism for hydrochloric acid, which may be due to its hydrophobic properties. 1-(Trimethoxysilyl)octane also has a high chemical stability, making it more useful than other glycol ethers for use in cleaning applications. 1-(Trimethoxysilyl)octane can be used as a fluorescent probe for fatty acids and boron nitride particles. 1-(Trimethoxysilyl)octane can also be used in human serum samples to detect the presence of hydroxyl groups on acyl chains with ft-ir spectroscopy.

Trimethoxy(octyl)silane

Alkyl Silane - Conventional Surface Bonding Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure. n-Octyltrimethoxysilane; Trimethoxysilyloctane Viscosity: 1.0 cStVapor pressure, 75 °: 0.1 mmTreatment for particles used in non-aqueous liquid dispersionsTrialkoxy silane
