Used primarily as an intermediate in organic synthesis, particularly in pharmaceutical manufacturing. It serves as a building block for modifying amine-containing compounds due to its ability to introduce the morpholine carboxylate group through alkylation reactions. Commonly employed in the development of bioactive molecules, including drug candidates targeting central nervous system disorders and anti-inflammatory agents. Its reactivity with nucleophiles makes it valuable in creating peptide mimetics and other structurally complex molecules in medicinal chemistry research.
