7H-Purine is a fundamental heterocyclic compound serving as the parent structure for purine bases in nucleic acids like DNA and RNA. It is widely used in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer drugs. It plays a crucial role in the production of nucleoside analogs, which are essential for treating viral infections such as HIV and hepatitis. Additionally, it serves as a building block in the creation of purine-based compounds for research in biochemistry and molecular biology. Its derivatives are utilized in the study of enzyme mechanisms and as inhibitors in various biochemical pathways. Furthermore, it is employed in the development of agrochemicals, contributing to the creation of herbicides and pesticides.
