Product Name: N,N'-BIS(SALICYLIDENE)ETHYLENEDIAMINE
Formula: C16H16N2O2
Synonyms: N,N′-Ethylenebis(salicylimine);2,2′-Ethylenebis(nitrilomethylidene)diphenol

CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Salcomine appears as a solid complex between the cobalt(II) ion and the condensation product of salicylaldehyde and ethylenediamine. Such condensation products are called "Schiff's bases." Complexation with cobalt nullifies their basic properties. Used as a catalyst for various oxidation reactions in which it behaves as an oxygen carrier.
Color/Form Red crystals from DMF
Solubility 27.6 [ug/mL] (The mean of the results at pH 7.4)
Stability/Shelf Life Stable under recommended storage conditions.
Decomposition When heated to decomposition it emits toxic fumes of /nitrous oxide/.
Other Experimental Properties Ionization energy (IE): 7.52 eV
Chemical Classes Nitrogen Compounds -> Other Aromatics (Nitrogen)
