N,N'-Bis(phenylmethyl)-1,2-ethanediamine Chemical Properties,Usage,Production

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).
