ACD/Structure Elucidator Suite

Are you doing everything you can with your structural data?

With ACD/Structure Elucidator Suite, scientists are able to perform rapid dereplication, advanced verification, speedily characterize structures using NMR and other techniques, and perform de novo elucidation for complex unknown structures.

With access to increasingly vast spectral libraries (including the PubChem database), Structure Elucidator Suite allows researchers to quickly find and verify chemical structures using experimental spectra, which have been previously identified (dereplication).

If a structure is not identified within the databases, scientists can then use the software to apply advanced algorithms and quantitatively evaluate the fit between a proposed structure and experimental spectra—even determining viable alternatives which may be a better match. The software includes a wide range of structure characterization and verification tools which are easily accessible.

For truly complex problems, Structure Elucidator Suite allows for de novo structure elucidation, generating a complete set of all structures which fit the correlations observed in the experimental data. It also supports the use of other analytical information to narrow down the structural possibilities—all helping to resolve structures more quickly and efficiently.

Capabilities

ACD/Structure Elucidator Suite includes all of the advanced processing and interpretive features and algorithms of ACD/NMR Workbook Suite and ACD/MS Workbook Suite. The key features of Structure Elucidator Suite are:

Vendor neutral analytical data processing for NMR, MS, UV/vis, FT-IR, and chromatography techniques
NMRSync—automatically synchronize peak picking and assignment across all spectra for a particular dataset
Dereplication—using internal and external libraries to search for previously determined structures

The internal library of ACD/Structure Elucidator Suite contains over 2 million structural fragments from ~410,000 compounds, and the software can also access the PubChem database. Searching these extensive databases 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".

Find starting points for structure elucidation using the internal structural fragment library
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 the stereochemistry of the structure using NOESY and/or ROESY data

Efficient Approaches for Addressing Spectral Ambiguities in Computer Assisted Structure Elucidation (CASE) Systems

In this poster by taking advantage of recent programming developments, we will present approaches that enable structure elucidation, under conditions where the initial data contains many ambiguous assumptions. Examples will be presented, and the strengths together with the limitations of each approach will be discussed.

New Structure Elucidation Tutorials

To accompany the new book, "Computer-Based Structure Elucidation from Spectral Data", we have released a free downloadable tutorial software package^* based on ACD/Structure Elucidator Suite. This software includes experimental spectra, allowing users to explore various CASE techniques, become familiar with the Structure Elucidator interface, and interact with the unique Molecular Connectivity Diagram.

^*The software is free for educational use only, and does not import new analytical data/spectra or save results to a database.
