Use
Purify trioxsalen by recrystallisation from CHCl3. If too impure, it is fractionally crystallised from CHCl3/pet ether (b 30-60o) using Norit and finally crystallised from CHCl3 alone to give colourless prisms, m 234.5-235o. It is a photosensitiser so it should be stored in the dark. [UV: Kaufmann J Org Chem 26 117 1961, Baeme et al. J Chem Soc 2976 1949, Beilstein 19/4 V 472.]
