Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to form stable amide and ether linkages. Also employed in the design of polymer materials for electronic applications, where its rigid structure contributes to thermal stability and favorable electronic properties. Its aromatic and heterocyclic framework makes it suitable for use in organic semiconductors and optoelectronic devices.
