Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of heterocyclic molecules with potential medicinal properties. Its functional groups—aldehyde and ester—allow for versatile chemical modifications, enabling the construction of complex molecular architectures. Commonly employed in research settings for creating pyrrole-based derivatives that show promise in antimicrobial, anti-inflammatory, or anticancer studies. Also utilized in organic synthesis to build advanced intermediates for drug discovery and in the preparation of specialty chemicals for agrochemical and material science applications.
