Used in organic synthesis as a key intermediate for pharmaceuticals and biologically active compounds. Serves as a building block in the preparation of heterocyclic compounds with potential medicinal properties. Applied in research for developing kinase inhibitors and anti-inflammatory agents. Also utilized in the study of indoline-based dyes and fluorescent probes due to its conjugated structure. Shows utility in medicinal chemistry for structure-activity relationship (SAR) studies targeting central nervous system disorders.
