Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of pyrimidine-based drugs such as antivirals and anticancer agents. It serves as a building block in the development of active pharmaceutical ingredients (APIs) due to its reactive ester group and aromatic heterocycle. Commonly employed in organic synthesis for constructing more complex pyrimidine derivatives. Also utilized in agrochemicals for the development of certain herbicides and plant growth regulators. Its versatility makes it valuable in medicinal chemistry research and development.
