Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building heterocyclic compounds. It is also employed in agrochemical research for developing new pesticides and herbicides due to its reactive amino and ester groups. Additionally, it serves as a building block in organic synthesis for creating complex thiophene-based dyes and functional materials.
