Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral, anticancer, and anti-infective agents. Its pyrimidine structure supports the construction of drug candidates such as nucleoside analogs and kinase inhibitors. Also employed in agrochemicals for the production of herbicides and plant growth regulators. Serves as a building block in organic synthesis for creating complex heterocyclic compounds with biological activity. The ester group enables further reactions, including hydrolysis or nucleophilic substitution, to generate desired derivatives.
