Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Its structure contains a reactive pyrrole ring and ester group, making it suitable for conjugation reactions, particularly in the development of dyes, fluorescent probes, and bioactive compounds. Commonly employed in the preparation of specialty polymers and as a building block in medicinal chemistry for designing kinase inhibitors and anticancer agents. Also utilized in click chemistry and Michael addition reactions due to its α,β-unsaturated carbonyl system.
