Toronto, Canada (March 5, 2009)—Advanced Chemistry Development, Inc., (ACD/Labs) developers of expert chemistry software, recently marked the one millionth download of their free chemical drawing package, ACD/ChemSketch Freeware. Now, the newest version of ChemSketch Freeware is available for...

New LC/MS and GC/MS deconvolution software makes confirming the presence of known compounds in messy samples faster and easier. Toronto, Canada (June 1, 2009)—ACD/Labs announces the release of new software for target analysis of complicated LC/MS and GC/MS datasets, without the tedious and difficult manual interpretation. ACD/IntelliTarget quickly confirms the presence or absence of known...

Sustainability is a growing concern in all aspects of life, and scientists have a unique role in finding solutions to environmental problems. One area where chemists can have a profound impact is the selection of catalysts.

Toronto, Canada (Dec. 17, 2010)—ACD/IXCR, ACD/Labs’ Intelligent Compound Recognition software, is being embraced by wastewater analysts for its non-targeted analyte detection and identification capabilities. It is particularly effective in aiding risk assessments and solving water emergencies quickly. This approach circumvents manual data interpretation, reducing the potential for error and affording analysts more time to focus...

For more than a decade, ACD/Structure Elucidator has been used by industry and academic experts to help solve some of the toughest structure problems. Using data from various analytical techniques (NMR, MS, UV, and IR) Structure Elucidator can propose chemical structures that are consistent with ALL available analytical data.

This month we re-visit the example of structure revision of Epohelmin A with structure revision utilizing ACD/Structure Elucidator Suite, which demonstrates how the software allows a researcher to avoid complex multi-stage synthesis to refute a wrong proposed structure and prove the revised one.

Studies aimed at the discovery of trace alkaloids in S. nux-vomica led Fu and co-workers to the isolation of Strynuxlines A and B, two novel alkaloids possessing an unprecedented skeleton with a 6/5/9/6/7/6 hexacyclic ring system. Here we will describe how Strynuxlines A (molecular formula C23H24N2O5) could be identified with the assistance of a CASE-based approach using ACD/Structure Elucidator Suite.

Due to their broad peaks and wide range of chemical shifts in 1H NMR spectra, exchangeable protons are known to pose challenges in NMR interpretation, but collecting 2D spectra and selecting proper experimental conditions can sometimes be used in our favor to learn more.
