PYRAZINE N-OXIDE Usage And Synthesis

Purification Methods

If the sample contains pyrazine-1-oxide, then place it in a Soxhlet extractor and extract it with hot pet ether (b 60-68o) in which the mono-oxide is soluble. Collect the dioxide from the thimble and recrystallise it from MeOH. It is dried in vacuo. It has at 1270cm-1 . [Koelsch & Gumprecht J Org Chem 23 1605 1958.]
