Widely used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in constructing pyrimidine-based drug candidates. Commonly employed in agrochemicals for the production of herbicides and pesticides due to its reactivity and stability. Also utilized in research laboratories for the preparation of fluorescent dyes and optical brighteners. Its nitro and chloro groups enable sequential substitution reactions, facilitating the creation of complex molecules in medicinal chemistry.
