Used in pharmaceutical research as a key intermediate for synthesizing biologically active compounds, particularly in the development of kinase inhibitors and antitumor agents. Its structure supports functionalization at multiple sites, making it valuable in medicinal chemistry for creating libraries of analogs in drug discovery. Also employed in the synthesis of heterocyclic compounds with potential antimicrobial and anti-inflammatory properties. Commonly utilized in cross-coupling reactions such as Suzuki and Heck reactions to build complex indolizine derivatives for biological screening.
