Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of thiazole-based drugs which exhibit antimicrobial, anti-inflammatory, and antiviral activities. It serves as a building block in medicinal chemistry for constructing biologically active molecules. Its ester and carboxylic acid functionalities allow for further derivatization, making it valuable in creating compound libraries for drug discovery. Also employed in the preparation of agrochemicals and functional materials due to its stable heterocyclic core.
