ChemSketch is a chemical structure drawing program developed by ACD/Labs. Among other features, ChemSketch has the ability to:[1]

  • Draw and view structures in 2D, or render in 3D to view from any angle
  • Draw reactions and reaction schemes, and calculate reactant quantities
  • Generate structures from InChI and SMILES strings
  • Generate IUPAC systematic names for molecules of up to 50 atoms and 3 ring structures
  • Predict logP for individual structures
  • Search for structures in the built-in dictionary of over 165,000 systematic, trivial, and trade names

ChemSketch uses many standard file formats for the import and export of drawings. The full list of available file formats can be found here, under the link "standard file formats." The program allows the user to draw chemical structures including organics, organometallics, polymers, and Markush structures.[1]

Users can download a freeware version of the software on the ACD/Labs website. The full version of the software is also available for purchase.
