Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Its structure features a carboxylic acid group, an ethoxycarbonyl ester, and a pyrrole ring, making it suitable for constructing complex heterocyclic systems. Commonly employed in the development of bioactive molecules, including potential drug candidates targeting inflammation, central nervous system disorders, and metabolic conditions such as diabetes. Also applied in the preparation of specialty polymers and ligands for metal coordination in catalysis.
