Used as an intermediate in the synthesis of azo dyes and pigments, particularly for producing bright and lightfast colorants used in textiles and inks. Plays a role in the manufacture of certain pharmaceuticals, including antiviral and anticancer agents, due to its pyrimidine backbone which is common in bioactive molecules. Also employed in agrochemical synthesis, especially in the development of herbicides and plant growth regulators. Its functional groups allow for easy modification in multi-step organic reactions, making it valuable in research and development of new chemical entities.
