Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and biologically active compounds. Its structure supports the construction of complex heterocyclic systems, making it valuable in medicinal chemistry for designing drug candidates. Commonly employed in reactions that form pyrrole-based frameworks, which are prevalent in anticancer, antimicrobial, and anti-inflammatory agents. Also utilized in the synthesis of functionalized porphyrins and other macrocyclic compounds for use in photodynamic therapy and materials science.
