Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrazole-based drugs with anti-inflammatory and analgesic properties. It serves as a building block in medicinal chemistry for designing compounds that target enzyme inhibition, such as COX-2 inhibitors. Its structure allows for easy functionalization, making it valuable in creating libraries of bioactive molecules for drug discovery. Also employed in agrochemical research for developing new pesticides and herbicides due to its ability to enhance metabolic stability in active ingredients.
