Description

{2-[2-(2-Methoxyethoxy)Ethoxy]Ethyl}Phosphonic Acid Diethyl Ester CAS NO 915376-46-4 is a specialized organophosphorus compound featuring a unique triethylene glycol monomethyl ether chain linked to a phosphonic acid diethyl ester group. This molecular architecture provides a valuable combination of polarity, solubility, and metal-chelating properties, making it a critical intermediate for advanced material synthesis. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring tailored ligands or functional monomers.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring phosphonate or phosphate ester functionalities.
• Agrochemical Synthesis: Used as a precursor for developing advanced herbicides, plant growth regulators, and other crop protection agents with enhanced systemic activity.
• Ligand for Metal Complexation: Acts as a chelating agent or ligand in catalytic systems and for metal ion extraction/separation processes due to its phosphonate group.
• Polymer & Material Science: Employed as a functional monomer or cross-linking agent to introduce phosphonate groups into polymers, modifying properties like adhesion, flame retardancy, or biocompatibility.
• Surface Modification Agent: Utilized to create self-assembled monolayers (SAMs) or to functionalize surfaces (e.g., metal oxides) for improved corrosion resistance or specific binding.
• Electrolyte Additive: Investigated for use in lithium-ion battery electrolytes to improve stability and cycle life at electrode interfaces.
