Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Serves as a building block in the development of kinase inhibitors and neuroprotective agents. Also applied in research related to central nervous system disorders due to its structural similarity to endogenous neurotransmitters. Employed in the preparation of fluorescent dyes and sensors owing to its indole-based scaffold. Common in medicinal chemistry for structure-activity relationship studies targeting neurological and inflammatory conditions.
