Pyrazin-2-ol is widely used in the pharmaceutical industry as a key intermediate in the synthesis of various drugs. It plays a crucial role in the development of antituberculosis medications, particularly in the production of pyrazinamide, which is a first-line treatment for tuberculosis. Additionally, it is utilized in the creation of other therapeutic agents, including those targeting bacterial and fungal infections. Beyond pharmaceuticals, pyrazin-2-ol is employed in agrochemical research for the development of pesticides and herbicides, contributing to crop protection and yield improvement. Its versatility also extends to organic synthesis, where it serves as a building block for creating complex molecules in research and industrial applications.
