Propanediamide (Malonamide) is a dicarboxylic acid diamide compound mainly used as an organic synthesis intermediate. It is applied in pharmaceutical intermediates, agrochemical synthesis, chelating agent research, specialty polymers, and fine chemical production. Due to its two amide functional groups, it is also used as a building block in the preparation of nitrogen-containing organic compounds.
