Diaminomaleonitrile Usage And Synthesis
  • Overview

    The importance of diaminomaleonitrile (DAMN) as a readily available and cheap building block for the synthesis of various nitrogen heterocycles has attracted the attention of organic chemists worldwide. An enormous number of research studies have focused on the preparation of various heterocycles that play a role in the pharmaceutical, cosmetics, dyes, and pigment industries, among others. This review details developments in the chemistry and reactions of DAMN over the last decade including novel methods utilised, new compounds prepared, and significant applications.

  • UsesDiaminomaleonitrile is a reagent used for the synthesis of 1,4-diazepine-2,3-dicarbonitrile dervatives. Also, it is used for the synthesis of Diaminomaleonitrile-based Schiff bases with a donor-acceptor structure and an aggregation-enhanced emission feature.
  • Solubility Information

    Solubility in water: 5g/L (25°C). Other solubilities: soluble in methanol, ethanol, dmf and dimethyl, sulfoxide, slightly soluble in ethyl ether and dioxane, insol. in benzene,acetone,xylene,toluene and cs2.

  • USES

    Diaminomaleonitrile (DAMN) is an organic compound composed of two amino groups and two nitrile groups bonded to a central alkene unit. The systematic name reflects its relationship to maleic acid.
    The chemical can be formed by polymerization of hydrogen cyanide and can be used as the starting point for the synthesis of several classes of heterocyclic compounds. Therefore, it has been considered as a possible organic chemical present in prebiotic conditions.
