Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and selective COX-2 inhibitors. It plays an important role in constructing pyrazole-containing bioactive molecules due to its ability to form amide and ester derivatives. Also utilized in agrochemicals for developing herbicides and fungicides, and in research for designing novel heterocyclic compounds with potential therapeutic activity.
