Yellow Crystalline Solid | [Uses]
4,6-Dichloro-5-nitropyrimidine (cas# 4316-93-2) is a compound useful in organic synthesis. | [Purification Methods]
If too impure, then dissolve it in Et2O, wash it with H2O, dry it over MgSO4, evaporate it to dryness and recrystallise it from pet ether (b 85-105o) to give a light tan solid. It is soluble in ca 8 parts of MeOH [Boon et al. J Chem Soc 96 1951, Montgomery et al. in Synthetic Procedures in Nucleic Acid Chemistry Zorbach & Tipson eds, Wiley & Sons, NY, p76 1968].
