Used as a building block in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its alkyne functionality allows for participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient conjugation in drug discovery and bioconjugation applications. The thiomorpholine ring contributes polarity and structural diversity, making it useful in the design of bioactive molecules. It may also serve as an intermediate in the synthesis of kinase inhibitors or other targeted therapies.
