Draw Chemical Structures, Reactions, Schematic Diagrams and more with ACD/ChemSketch
ACD Labs Logo


  • Space

    Draw a wide variety of chemical structures; use the built-in templates to insert pre-drawn structures

  • Space

    Generate IUPAC names (for molecules of up to 50 atoms and 3 ring structures), InChI codes, and SMILES strings for structures

  • Space

    Draw reaction schemes and display summarized properties for the reaction elements

  • Space

    Use the built-in Dictionary to search for structures by name fragment

  • Space

    Predict molecular properties for individual structures (including molecular weight, formula weight, density, and logP)

A Complete Software Package for Drawing Chemical Structures

ACD/ChemSketch is a chemically intelligent drawing interface that allows you to draw almost any chemical structure including organics, organometallics, polymers, and Markush structures. Use it to produce professional looking structures and diagrams for reports and publications.

  2. You can still input structures from unsupported formats by opening the file with another program and pasting it into ACD/ChemSketch as an OLE object

  • I find the ACD/ChemSketch software to be very intuitive. Furthermore, it appears to seamlessly integrate with other Microsoft Office programs, such as Word. Thomas J. Siepmann, Attorney; Birch, Stewart, Kolasch, & Birch, LLP
  • We use ChemSketch to draw structures to add detail to our publications and grant applications. ...the ability to illustrate [fine structural] differences really adds to them. Professor Jane Grande-Allen, Assistant Professor of Bioengineering, Rice University
  • We are satisfied with ACD/ChemSketch as it perfectly fits our enterprise environment, it is manageable, and provides an excellent chemical drawing suite for our users. Mr. Vince Szucs, IT Director, Gedeon Richter
