Ethylenediamine dihydrochloride Usage And Synthesis

Chemical Properties

white crystalline powder

Uses

Ethylenediamine dihydrochloride is used as stabilizer in steroid creams and rubber latex; inhibitor in antifreeze solutions and cooling fluids; in floor-polish remover; in nystatin cream and aminophylline; epoxy-curing agent; accelerator in color development baths in photography; in veterinary preparations; in electroplating and electrophoretic gels, dyes, fungicides, insecticides, synthetic waxes, textile lubricants, and eye and nose drops; solvent for casein, albumin, shellac.

Uses

Ethylenediamine dihydrochloride was used in modified ethylenediamine condensation method for fluorimetric determination of catecholamines. It was used to investigate the luminescence properties of complexes of Eu^III and Tb^III with ethylenediamine. It was used in the synthesis of 1,3,5-tris(4,5-dihydro-1H-imidazol-2-yl)benzene.

Definition

ChEBI: A hydrochloride that is the dihydrochloride of ethylenediamine.

Safety Profile

Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. When heated to decomposition it emits very toxic fumes of HCl and NOx.

Purification Methods

Crystallise the salt from H2O or H2O/EtOH. Wash the crystals with EtOH and dry them in vacuo. It sublimes on heating. [Beilstein 4 IV 1168.]
