Used primarily as a surface modifier in the production of self-assembled monolayers (SAMs) on silicon-based substrates, especially in microelectronics and semiconductor manufacturing. It imparts hydrophobic properties to surfaces, making them water-repellent, which is beneficial in moisture-sensitive devices. Commonly applied in the fabrication of biosensors and microfluidic devices where surface energy control is critical. Also utilized in chromatography as a stationary phase modifier to enhance separation efficiency. Its amine functionality allows further chemical derivatization, enabling use in bioconjugation and immobilization of biomolecules on solid supports.
