Description

Peg3-Bis-(Ethyl Phosphonate) CAS NO 160625-24-1 is a specialized organophosphorus compound featuring a polyethylene glycol (PEG) spacer linked to two ethyl phosphonate groups. This unique bifunctional structure makes it a valuable intermediate for constructing complex molecular architectures, particularly in advanced materials and pharmaceutical research. It is essential for scientists and engineers in the fields of polymer chemistry, bioconjugation, and ligand synthesis who require precise control over molecular spacing and functional group presentation.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, targeted drug delivery systems, and as a linker for bioconjugation.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce phosphonate groups into polymers, enhancing properties like flame retardancy or metal chelation.
• Ligand Synthesis: Serves as a precursor for creating chelating agents and ligands for catalysis or metal ion sequestration.
• Surface Functionalization: Employed to modify material surfaces (e.g., nanoparticles, sensors) with phosphonate groups for improved stability, biocompatibility, or specific binding.
• Materials Science: Key building block for developing novel organic-inorganic hybrid materials and metal-organic frameworks (MOFs).
• Research & Development: A versatile tool in academic and industrial R&D for exploring new chemical entities and material properties.
