9H-Purine, 6-chloro-9-[2-deoxy-2-fluoro-3, 5-BIS-O -(tetrahydro-2H-pyran-2-yl) -β-D-Ribofuranosyl] is an important intermediate in chemical synthesis. Can be used to prepare a range of other compounds. For example, it can be used to prepare 9-alkyl purines and 6-mercaptopurine. In addition, 6-Chloropurine has been shown to exhibit antitumor activity in combination with azaserine in multiple mouse tumor models
