Used as a key intermediate in the synthesis of pyrazole-based pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and kinase inhibitors. Its ester functionality allows for easy modification in multi-step organic syntheses, making it valuable in medicinal chemistry for creating biologically active compounds. Also employed in agrochemical research for designing new pesticides and herbicides due to the pyrazole ring’s favorable binding properties with biological targets.
