Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and fine chemicals. It serves as a building block in the development of indole-based compounds, which are common in medicinal chemistry due to their biological activity. Commonly employed in the synthesis of tryptamine derivatives and other psychoactive substance analogs for research purposes. Also utilized in the preparation of dyes and fluorescent compounds due to the indole core’s favorable electronic properties. Its acetyl groups allow for further functionalization, making it valuable in multi-step synthetic routes.
