Hazard Information	Back Directory
[Chemical Properties] light yellow liquid
[Uses] N,N'-Dibenzylethylenediamine is an intermediate of cephalosporin and penicillin.
[Definition] ChEBI: Benzathine is a diamine. It is a conjugate base of a benzathine(1+).
[Synthesis Reference(s)] The Journal of Organic Chemistry, 55, p. 3209, 1990 DOI: 10.1021/jo00297a042
[Safety Profile] Poison by ingestion,intraperitoneal, and parenteral routes. When heated todecomposition it emits toxic vapors of NOx.
[Purification Methods] Dissolve DBED in acid, extract with toluene, basify, extract it with Et2O, dry over solid KOH, evaporate and fractionate it in vacuo. The diacetate crystallises from H2O by addition of EtOH and has m 111o (solubility in H2O is ~25%). The dihydrochloride has m 306-308o (from H2O) and the dipicrate has m 212o(dec) (from H2O).
