Used in the synthesis of sulfa drugs, particularly as an intermediate in the production of sulfadiazine, which is an antibacterial agent effective against a range of infections. Also serves as a building block in the preparation of certain antiviral and anticancer compounds. Its structure supports coordination with metal ions, making it useful in some catalytic applications and in the development of metal-organic frameworks. Additionally, it finds use in research for designing enzyme inhibitors due to its similarity to pyrimidine bases in biological systems.
