Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs with anti-inflammatory, antiviral, and anticancer properties. Its structure allows for easy modification, making it valuable in medicinal chemistry for building bioactive molecules. Commonly employed in the preparation of pyrazole-containing compounds that exhibit kinase inhibition, which is relevant in targeted cancer therapies. Also utilized in agrochemical research for developing pesticides and herbicides due to its ability to enhance biological activity in active ingredients.
