Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for treating inflammatory diseases and certain cancers. Its structure supports the design of small molecule drugs that modulate enzyme activity. Commonly employed in medicinal chemistry research for optimizing lead compounds due to its favorable reactivity and ability to form derivatives with enhanced biological activity. Also utilized in the preparation of pyrazolopyrimidine-based compounds showing potential as antiviral and antiproliferative agents.
