4-amino-7-iodopyrrolo2,1-f1,2,4triazine丨CAS 1770840-43-1

4-Amino-7-iodopyrrolo[2,1-f][1,2,4]triazine is a specialized heterocyclic intermediate widely used in pharmaceutical and medicinal chemistry research. It serves as a building block for the synthesis of nucleoside analogs, kinase inhibitors, and antiviral compounds. Its iodinated position provides a reactive site for palladium-catalyzed cross-coupling reactions, such as Suzuki, Sonogashira, or Buchwald-Hartwig reactions, enabling the construction of diverse functionalized derivatives. This compound is particularly valuable in drug discovery programs targeting cancer, viral infections, and other therapeutic areas where heterocyclic scaffolds are essential for biological activity. It is also utilized in the development of fluorescent probes and bioactive heterocycles for biochemical studies.

The primary benefits of this compound stem from its structural versatility and high reactivity at the iodinated position. The combination of the amino group and the iodine atom allows selective functionalization, facilitating the rapid synthesis of complex derivatives. Its heterocyclic framework supports the design of molecules with high biological relevance, while the iodine substituent enables efficient cross-coupling reactions, improving yield and synthetic flexibility. Additionally, its stability and purity make it suitable for research-scale and larger synthetic applications, providing a reliable intermediate for pharmaceutical and chemical innovation.
