Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for easy functionalization, making it valuable in creating biologically active molecules. Commonly employed in medicinal chemistry for constructing pyrazole-containing compounds with potential anti-inflammatory, antiviral, and anticancer activities. Also utilized in agrochemicals for designing new active ingredients due to its favorable reactivity and stability in various chemical transformations.
