Used in organic synthesis, particularly in the development of pharmaceuticals and biologically active compounds. Its structure serves as a key building block for nitrogen-containing heterocycles, which are common in drug design. It is especially valuable in the synthesis of kinase inhibitors and other medicinal agents targeting neurological and inflammatory conditions. Also employed in research settings to develop fluorescent probes due to its photophysical properties. Commonly utilized in the preparation of indole-based analogs for structure-activity relationship studies.
