Pyrimidine-2-carbothioamide finds application in the field of medicinal chemistry, where it serves as a key intermediate in the synthesis of various biologically active compounds. It is particularly useful in the development of antiviral and anticancer agents due to its structural similarity to pyrimidine, a fundamental component of nucleic acids. Researchers utilize this compound to design and synthesize derivatives that can inhibit enzymes or interfere with DNA/RNA replication in pathogens or cancer cells. Additionally, it is employed in the preparation of thioamide-based drugs, which are known for their therapeutic potential in treating diseases like tuberculosis. Its versatility also extends to agrochemical research, where it contributes to the creation of novel pesticides and herbicides.
