Hazard Information

Chemical Properties
white to almost white crystalline powder
Purification Methods
It is purified by crystallisation from absolute EtOH (slight decomposition) until it has only a slight odour. Store it in well-stoppered containers because it is very hygroscopic. It is very soluble in H2O, AcOH and glycerol but slightly soluble in EtOH (0.66%). It forms water-soluble hydrazones with carbonyl compounds. [Beilstein 4 III 1133.]
