What’s New in Name Version 2021

Version 2021 of Name adds new features, including extended support for naming of nitrogen compounds, and improves existing ones. Read below for details, and contact us for help upgrading your software.

Enhancements to IUPAC Name Generation

  • We improved the recognition of stereoisomers for structures with nitrogen in atropisomeric bonds

    Version 2021: (1P)-1-(1,3-dimethylnaphthalen-2-yl)-1H-indole
    Previous version: 1-(1,3-dimethylnaphthalen-2-yl)-1H-indole
  • We improved citation and use of brackets for multiplied substituent groups.
    Version 2021: [oxybis(2,5-dihydrofuran-2,4-diyl)]dimethanol
  • Previously refused specific arrangements of carbohydrate units are now named according to organic nomenclature
    Version 2021: (2R,3R,4S,5R)-2-{1′-[(2S,3S,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl][3,3′-bipyrrolidin]-1-yl}-5-(hydroxymethyl)oxolane-3,4-diol
  • We improved use of prime symbols for nitrogen locants in some functional groups.

Enhancements for Name to Structure Generation

  • Extra punctuation marks are ignored when generating chemical structures from names.
  • We improved structure generation for anion names that include numeral prefixes (i.e., hexafluorophosphate) and for metals with variable valences.
  • You can now import/export data from/to ChemDraw .cdxml files.

As always, ChemSketch is included with Name so you can draw any chemical structure. We’ve improved features for ChemSketch as well:

More Data Types Can Be Included in Database Records

  • You can now represent large/complex molecules using graphical objects with defined formulas and modify them by attaching traditional chemical structures. The entire structure may be used in calculations and searches.

    Represent complex molecules with graphical objects, e.g., proteins, antibody-drug conjugates, nanoparticles on surfaces, etc.

Graphical Templates Added

  • We included templates for Viruses & Vaccines (including the Covid-19 Virus) and Laboratory Animals.

    New templates added for viruses, vaccines, and laboratory animals

3D Viewer Improvements

  • Create animated gifs from drawn structures

InChI Updated to Latest Version

  • We added support for InChI version 1.06
