Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrimidine-based drugs such as antivirals and antitumor agents. Its structure supports the construction of biologically active molecules by serving as a building block for substituted pyrimidines. Commonly employed in medicinal chemistry for scaffold modification and optimization of drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its favorable reactivity and ability to form diverse derivatives.
