LIGHT YELLOW CRYSTALLINE POWDER | [Uses]
2-Chloro-3,5-dinitropyridine is used as efficient pie electron acceptor in the preparation of charge transfer complexes with aniline and its derivatives acting as donors. | [Purification Methods]
Dissolve it in CHCl3, shake it with saturated NaHCO3, dry (MgSO4), evaporate and apply to an Al2O3 column, elute with pet ether (b 60-80o), evaporate and recrystallise it from *C6H6 or pet ether.
