It is a colorless liquid with a fishy odor. It features two secondary amine functional groups. ReactionsDMEDA is used as a chelating diamine for the preparation of metal complexes, some of which function as homogeneous catalysts.[1][2] The compound is used as a precursor to Imidazolidines by condensation with ketones or with aldehydes: RR'CO + C{{sub|2}}H{{sub|4}}(CH{{sub|3}}NH){{sub|2}} → C{{sub|2}}H{{sub|4}}(CH{{sub|3}}N){{sub|2}}CRR' + H{{sub|2}}O See also
