Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and anticancer agents. Its structure supports the development of pyrimidine-based drugs, which are common in treatments targeting nucleic acid synthesis. It is also employed in the preparation of agrochemicals, including certain herbicides and plant growth regulators. Additionally, it serves as a building block in the creation of functional dyes and optical brighteners due to its conjugated aromatic system. Its amino and ester functionalities allow for easy modification in multi-step organic syntheses.
