What is GChemPaint

Chemical drawing tools

Evaluation criteria

In order to be able to evaluate the following programs correctly, I will try to draw a grape sugar molecule with each of these programs. The programs are then assessed under the following aspects:

  • Export options (PNG, JPG, SVG) - Is the resolution high?
  • Intuitive operation: can you use the program without reading the operation?
  • GUI: Is the interface well structured?
  • Structures: Can you depict different types of bonds?
  • Import options: can the files be exported as mol, cdx, pdb, ...?
  • Templates: Are certain structures already prepared?

Tools for Ubuntu

ChemTool 1.6.10


sudo apt-get install chemtool


Chemical structures can be easily drawn with ChemTool. What I am missing here, however, is a functioning export to JPG / PNG format and a possibility to draw free electron pairs.
