Used as an intermediate in organic synthesis, particularly in the preparation of functionalized polymers and surfactants. It serves in the modification of silica surfaces and other materials requiring alkyl chain spacers with ether functionalities. Commonly employed in the synthesis of ionic liquids and phase-transfer catalysts due to its ability to introduce methoxyethoxy groups that enhance solubility and flexibility in molecular structures. Also utilized in pharmaceutical research for constructing drug delivery systems where controlled hydrophilicity and linker length are important.
