Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It plays a key role in the preparation of indomethacin and related compounds due to its ability to form ester and amide derivatives that exhibit anti-inflammatory and analgesic properties. Also utilized in organic synthesis for constructing heterocyclic systems and in the development of agrochemicals as a building block for herbicides and plant growth regulators. Its reactivity allows for easy functionalization, making it valuable in medicinal chemistry research and drug discovery processes.
