Description

3,6,9,12,15,18-Hexaoxaeicosane-1,20-Diamine is a high-purity, hydrophilic polyether diamine with a long, flexible ethylene oxide spacer chain. This compound matters as a versatile, water-soluble building block for creating advanced materials with tailored properties. It is primarily needed by manufacturers in the polymer, pharmaceutical, and specialty chemical industries for applications requiring biocompatibility, flexibility, and controlled reactivity.

Application

• Polymer Synthesis: A key monomer for producing hydrophilic polyurethanes, polyamides, and polyurea elastomers with enhanced flexibility and moisture resistance.
• Bioconjugation & Drug Delivery: Used as a PEGylated linker or spacer arm for coupling bioactive molecules, proteins, and diagnostics, improving solubility and circulation time.
• Surface Modification: Acts as a functional coating agent to introduce amine groups onto surfaces, improving adhesion, wettability, and biocompatibility of materials.
• Crosslinking Agent: Serves as a water-soluble crosslinker for epoxy resins, hydrogels, and adhesives, contributing to tunable mechanical strength and swelling properties.
• Chelating Ligand Precursor: The amine termini can be functionalized to create macrocyclic or polymeric ligands for metal ion complexation and catalysis.
• Personal Care & Cosmetics: Employed in the formulation of advanced hair and skin care products as a conditioning and film-forming agent.
