ACD/Structure Elucidator Suite

Efficiently resolve unknown structures that are consistent with ALL experimental data


Click to enlarge

Structure Elucidator Suite is a complete software package that helps in the elucidation of unknown structures. It extracts information from various analytical techniques (NMR, MS, UV-IR, and chromatography) in all instrument formats to generate potential structures that are consistent with the data provided.

The software can improve your elucidation workflow in a variety of ways: by generating a complete set of all structures that fit the experimental data; by offering viable alternatives to a proposed structure; and by supporting the use of other analytical information to narrow down the structural possibilities—all helping to resolve structures faster and more efficiently.

  • Dereplication of known compounds—search the internal library of 2 million structural fragments.
    The internal library of ACD/Structure Elucidator Suite contains over 2 million structural fragments from ~410,000 compounds. Searching this extensive database before getting stuck into an elucidation will save time in the identification of known fragments consistent with the analytical data. Download our application note to learn more about applying this library in dereplication: "Dereplication of a Natural Product by NMR: A Three Stage Approach".
  • Computer assisted structure elucidation (CASE) using NMR, MS, UV-IR, and chromatography data.
  • NMRSync—automatically synchronize peak picking and assignment across all spectra for a particular dataset.
  • Structure evaluation—automatically compare predicted and experimental NMR spectra and receive a match factor.
  • Database experimental spectra, chemical structures, analysis results, and user data and notes.
  • Determine relative stereochemistry—optimize structures in 3D and determine stereochemistry with NOESY and ROESY data.
