General description
Triethoxy(octyl)silane (OCTEO) is a high-reactivity organosilane coupling agent designed for the molecular-level modification of surface
Its molecular structure features an 8-carbon octyl chain and three hydrolytically sensitive ethoxy groups. This architecture ensures the formation of stable, covalent siloxane bonds with inorganic substrates while providing a low-energy, hydrophobic surface with water contact angles often exceeding 150°.
In the realm of nanoelectronics, it serves as an essential "hydrophobization" agent, reducing non-specific binding and preventing water-induced charge leakage in sensitive micro-electronic components.
Refined to a 97% high-purity specification, this grade is optimized for consistency in research and industrial processes requiring reliable, reproducible surface functionalization for point-of-care (POC) diagnostics and molecular-scale circuitry.

Application
As a high-performance alkoxysilane, OCTEO is used to engineer precise hydrophobic interphases and moisture-resistant layers in advanced diagnostic and electronic systems.
Semiconductor Passivation: Utilized to form dense, moisture-resistant Self-Assembled Monolayers (SAMs) on inorganic substrates like silicon and glass. These layers provide critical insulation and protection for semiconductor devices against environmental degradation.
Gas-Phase Biosensing: Employed in the fabrication of low-cost colorimetric sensor arrays. It stabilizes the porosity of sensor substrates, enabling rapid color changes for the real-time detection of toxic gases.
Biomolecule Immobilization: Used in the production of organically modified silane (Ormosil) nanoparticles. These nanostructures can encapsulate enzymes like horseradish peroxidase (HRP), preserving their activity for high-sensitivity biochemical assays.
Micro-patterning & Adhesion: Acts as an adhesion promoter between organic resins and inorganic micro-electrode arrays. Its ability to modulate surface energy is critical for the reliable performance of printed circuit boards (PCBs) and flexible bio-interfaces.
