Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive bromo group, which allows for further functionalization through cross-coupling reactions. Commonly employed in the preparation of biologically active molecules targeting tyrosine kinases and other enzyme systems involved in signal transduction pathways. Its morpholine ring enhances solubility and binding affinity, making it valuable in optimizing drug candidates for improved pharmacokinetic properties.
