Description

2-((2-(2-(2-Methoxyethoxy)Ethoxy)Ethoxy)Methyl)Oxirane CAS NO 73692-54-3 is a specialized, high-purity polyether glycidyl ether derivative, valued for its reactive oxirane (epoxide) functionality and hydrophilic poly(ethylene glycol) chain. This compound is a critical building block for introducing reactive sites and modifying surface properties in advanced polymer systems. It is essential for R&D and production in industries requiring customizable polymer chemistry, such as specialty coatings, adhesives, and biomedical materials.

Application

• Crosslinking Agent & Polymer Modifier: Used to introduce reactive epoxide groups into polymer backbones for crosslinking, enhancing mechanical strength, chemical resistance, and thermal stability in coatings, adhesives, and composite resins.
• Surface Functionalization: Employed to modify material surfaces (e.g., nanoparticles, silicon wafers, membranes) to improve hydrophilicity, biocompatibility, or to provide anchor points for further chemical grafting.
• Bioconjugation & Pharmaceutical Intermediates: Serves as a versatile linker for coupling biomolecules (proteins, peptides) or drugs to PEGylated carriers in drug delivery system development and diagnostic assays.
• Hydrogel Synthesis: Acts as a key monomer or crosslinker in the fabrication of hydrophilic and biocompatible hydrogels for biomedical applications, including tissue engineering scaffolds and contact lenses.
• Lubricant & Surfactant Intermediate: Utilized in the synthesis of advanced polyether-based lubricants and non-ionic surfactants, where its structure imparts desirable solubility and surface-active properties.
• Epoxy Resin Formulation: Incorporated as a reactive diluent or flexibilizer in epoxy resin formulations to reduce viscosity and modify the cured network's properties for electronic encapsulation or structural adhesives.
