Used in organic synthesis as a building block for creating more complex molecules, particularly in the development of pharmaceuticals and agrochemicals. It serves as a key intermediate in the production of compounds with potential biological activity, such as inhibitors or receptor modulators. Its indole structure makes it valuable in the study of serotonin-related pathways, contributing to research on neurological disorders. Additionally, it is employed in the synthesis of fluorescent dyes and other materials for analytical and industrial applications.
