6-Chloro-7-deazapurine (Cat No.: R001015) is a heterocyclic compound structurally related to purines, with a chlorine atom at the 6-position and the nitrogen at position 7 replaced by carbon, hence the name “7-deaza.” This modification alters its electronic and hydrogen bonding properties, making it a valuable building block in nucleoside analog synthesis. It is often used in the development of antiviral and anticancer agents, as well as in nucleic acid research for studying base-pairing behavior and enzyme interactions in modified DNA or RNA.
