| | Pteridine (6CI,7CI,8CI,9CI) Usage And Synthesis |
| Definition | ChEBI: Pteridine is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of pteridines. | | Purification Methods | It crystallises from EtOH, *benzene, n-hexane, n-heptane or pet ether. It is best purified by sublimation at 120-130o/20mm. Store at 0o, in the dark. It turns green in the presence of light and on long standing in the dark and sublimation leaves the dark-coloured material behind. [Albert et al. J Chem Soc 474 1951; see Albert & Armarego Adv Heterocycl Chem 4 1 1965, Beilstein 26 III/IV 1770.] |
