Chemical Properties

white to light yellow crystalline solid

Purification Methods

Recrystallise the bromide from EtOH, CHCl3 or diethyl ether, or recrystallise it from acetonitrile and dry it over P2O5 under reduced pressure for several days. It also recrystallises from EtOH/diethyl ether (1:2), EtOAc, water or boiling MeOH/acetone (1:3) or by adding an equal volume of acetone and allowing to cool. Dry it at 100o in vacuo for 12 days, and store over P2O5. [Beilstein 4 IV 332.]
