Formamidine acetate Usage And Synthesis |
Chemical Properties |
white to light yellow crystalline powder |
Purification Methods |
Unlike the hydrochloride, the acetate salt is not hygroscopic. It is recrystallised from a small volume of acetic acid, by addition of EtOH and the crystals are washed with EtOH then Et2O and dried in a vacuum. [Taylor et al. Org Synth 46 39 1966, Beilstein 2 IV 82.] |
