This is a specialty organic intermediate featuring a terminal alkyne and a hydrophilic 2-methoxyethoxy group. It is primarily used in organic synthesis as a building block for click chemistry (CuAAC reactions) to form 1,2,3-triazoles, enabling bioconjugation, biomolecule labeling, and modification for pharmaceutical research and drug development. It also serves as a linker in the synthesis of functional polymers, dendrimers, and advanced materials with enhanced solubility and biocompatibility. Its applications extend to materials science for creating coatings and self-assembling structures.
