Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceutical compounds. Its structure allows for selective functionalization, making it valuable in the creation of bioactive molecules. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to build complex aromatic systems. Also utilized in medicinal chemistry for constructing modulators of central nervous system targets due to the presence of the morpholine ring, which can improve solubility and bioavailability. Shows utility in the synthesis of kinase inhibitors and receptor antagonists in research settings.
