| Purification Methods | Purify it by salting out three times from an aqueous solution with sodium acetate, followed by repeated extraction with EtOH [McGrew & Schneider J Am Chem Soc 72 2547 1950]. It is a green powder that is slightly soluble in Me2CO, EtOH and pyridine. It is soluble in conc H2SO4 to give a blue solution that becomes turquoise on dilution. [Allen et al. J Org Chem 7 63 1942, Beilstein 14 H 725.] | |||||||||||||||||||||||||||||||||
