Description

2-(2-(2-Methoxyethoxy)ethoxy)ethylamine (CAS 163931-61-1) is a high-purity, polyether-functionalized amine with the molecular formula C₇H₁₇NO₃. This versatile compound features a hydrophilic triethylene glycol monoether backbone terminated by a reactive primary amine group, making it an excellent linker or modifier for surface functionalization, bioconjugation, and polymer synthesis. Its unique structure combines the solubility-enhancing properties of oligoethylene glycol with the reactivity of an aliphatic amine. Supplied as a clear, colorless to pale yellow liquid, this product is rigorously tested to ensure consistency in purity (>98%), molecular weight (175.22 g/mol), and performance. Ideal for advanced material science, pharmaceutical research, and nanotechnology applications where controlled amine reactivity and water solubility are required.

Application

This compound is widely used as a building block for synthesizing functionalized surfaces, particularly in biosensor and microarray technologies where its ethylene oxide spacer provides optimal probe accessibility. The amine terminus enables conjugation with carboxylic acids, isocyanates, and other electrophiles under mild conditions. Researchers employ it to modify nanoparticles, dendrimers, and hydrogels for biomedical applications due to its biocompatibility and PEG-like properties. It also serves as a key intermediate in the preparation of non-ionic surfactants and specialty polymers.
