General description
This 95% pure alkanethiol is ideal for establishing stable molecular layers via van der Waals forces. While containing trace amounts of related organic species, it provides sufficient molecular orientation for general diagnostic development and academic research in surface science.
Application
- Benchtop Research: Widely used in laboratory settings for the functionalization of gold nanoparticles and flat gold substrates.
- Industrial SAMs: Effective for creating protective Self-Assembled Monolayers (SAMs) on noble metals to prevent corrosion or to act as an adhesion promoter for organic top-layers.
- Secondary Functionalization: The terminal carboxylic acid remains available for coupling with larger molecules, making it a versatile tool for general biochemical assays.
