Used in organic synthesis as a building block for pharmaceuticals and functional materials, particularly in the development of conjugated systems for optoelectronic devices. Its ethynyl group enables click chemistry reactions, such as cycloadditions with azides, making it valuable in drug discovery and bioconjugation.

The morpholine moiety enhances water solubility and cell membrane permeability, making it popular in research for creating targeted molecules, such as enzyme inhibitors or drug delivery agents.

Also employed in materials science as an intermediate to construct liquid crystals and polymers with tailored electronic properties, including conductivity and luminescence.
