Description

2-[2-[2-(3-Aminopropoxy)Ethoxy]Ethoxy]Ethanol is a versatile, multi-functional amine-terminated polyether glycol. This compound matters as a critical building block and reactive intermediate, offering a unique combination of a hydrophilic polyether chain with a primary amine group for further chemical modification. It is essential for industries requiring custom synthesis, surface modification, and the creation of specialty polymers. Its structure makes it particularly valuable for applications demanding water solubility, flexibility, and a reactive site for cross-linking or conjugation.

Application

• Polymer Synthesis: Key monomer for producing polyurethanes, polyamides, and epoxy curing agents, imparting flexibility and hydrophilicity to the final polymer.
• Surface Modification & Coatings: Used as a coupling agent or surface-active component to improve adhesion, wetting, and anti-fog properties in coatings, inks, and adhesives.
• Bioconjugation & Pharmaceutical Intermediates: Serves as a hydrophilic linker (PEG spacer) for drug delivery systems, diagnostic agents, and protein-polymer conjugates.
• Personal Care & Cosmetics: Functions as a humectant, emulsifier, or viscosity modifier in advanced skincare and haircare formulations.
• Lubricants & Functional Fluids: Acts as a base fluid or additive in synthetic lubricants and hydraulic fluids, offering stability and low toxicity.
• Chemical Research & Development: A valuable reagent for organic synthesis and material science research, enabling the creation of novel functional materials.

Quality Control

Our 2-[2-[2-(3-Aminopropoxy)Ethoxy]Ethoxy]Ethanol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay (by titration or HPLC), identity confirmation (IR), and impurity profiling, to ensure it meets high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation.
