Sicherheit

Pteridine (6CI,7CI,8CI,9CI) Chemische Eigenschaften,Einsatz,Produktion Methoden

l?uterung methode

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.]
