LIGHT YELLOW FLUFFY POWDER | [Purification Methods]
If impure and discoloured, then chromatograph it through Al2O3 and elute with *C6H6/hexane (1:1) containing 1% MeOH. The fractions are followed by TLC on Al2O3 (with Dragendorff's reagent for detection: RF 0.6 in the above solvent system). Recrystallise the residues from the required fractions from *C6H6/hexane to give yellowish leaflets. It complexes with Na or K ions with logKNa 3.95 and logKK 4.71.
