Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of pyrrole-based drugs. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. It is also employed in the preparation of dyes, pigments, and specialty polymers due to the electron-rich nature of the pyrrole ring. Additionally, it serves as a building block in agrochemicals and in the design of organic electronic materials.
