Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding and modification in drug design, making it valuable in medicinal chemistry research. It is also employed in the preparation of bioactive molecules with potential antitumor and anti-inflammatory properties. Due to the presence of reactive functional groups, it facilitates coupling reactions and derivatization in organic synthesis, especially in the construction of complex heterocyclic systems.
