Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. It also serves as a building block in the preparation of bioactive molecules and functional materials due to its heterocyclic structure. Its amino group allows for easy modification, enabling the creation of derivatives for use in medicinal chemistry and drug discovery. Additionally, it finds application in the design of organic semiconductors and fluorescent probes owing to its electron-rich aromatic framework.
