N-(2-Aminoethyl)-3-aminopropyltriethoxysilane is an organosilane coupling agent that contains both amino (-NH₂) groups and ethoxy (-OEt) groups attached to a propyl chain (-CH₂CH₂CH₂NH₂).
Here are the key aspects of N-(2-Aminoethyl)-3-aminopropyltriethoxysilane:
The molecule consists of:
Aminoethyl group (-CH₂CH₂NH₂): Provides primary amine functionality, making it reactive towards various substrates.
Aminopropyl group (-CH₂CH₂CH₂NH₂): Adds additional amine functionality, enhancing its reactivity.
Triethoxysilane group (-Si(OEt)₃): This group is hydrolysable, allowing it to form strong bonds with inorganic surfaces.
