Description

1,14-Diamino-3,6,9,12-Tetraoxatetradecane is a specialized polyether diamine compound, recognized by the CAS number 68960-97-4. This chemical is valued for its bifunctional nature, combining a flexible polyether backbone with reactive primary amine termini, making it a versatile building block for advanced material synthesis. It is essential for researchers and manufacturers in the polymer, pharmaceutical, and specialty chemical industries seeking to create tailored products with specific properties.

Application

• Polymer Modification: Acts as a chain extender or curing agent in the synthesis of polyurethanes, polyureas, and epoxy resins, imparting flexibility and improved chemical resistance.
• Pharmaceutical Intermediates: Serves as a key precursor in the synthesis of complex drug molecules, particularly where a hydrophilic linker is required.
• Surface-Active Agents: Used in the formulation of surfactants and demulsifiers for industrial and oilfield applications.
• Chelating Ligand Synthesis: The polyether chain and amine groups make it a useful starting material for creating macrocyclic or acyclic ligands for metal ion complexation.
• Crosslinking Agent: Employed in the production of hydrogels, coatings, and adhesives where controlled crosslink density is critical.
• Bioconjugation: Utilized as a heterobifunctional linker for attaching molecules, such as drugs or dyes, to proteins, peptides, or other biomolecules.
