Used primarily as an alkylating agent in organic synthesis, this compound is valuable for introducing the 2-methoxyethyl group into various substrates. It is commonly employed in the preparation of pharmaceutical intermediates, where its sulfonate ester functionality allows for efficient nucleophilic substitution reactions. Due to the stability and reactivity of the tosylate leaving group, it facilitates the formation of C–O, C–N, and C–C bonds under mild conditions. It is also utilized in the synthesis of functionalized polymers and surfactants, where the methoxyethyl chain contributes to solubility and biocompatibility. Its application extends to agrochemicals and specialty chemicals requiring ether-linked side chains with controlled polarity.
