  • Applications

    N-Ethylsuccinimide (CAS 2314-78-5) is mainly used as an organic synthesis intermediate to access imide-containing compounds; real-world applications include serving as a precursor for pharmaceutical and agrochemical intermediates, as well as a building block for dye-related and color-intermediate compounds, and as a precursor for polymer and polyimide materials; it is also evaluated for use in coatings and inks formulations and in electronics-related material development on a research and development basis.
