This chemical drawing program is the ‘front end’ used forrunning molecular calculations with ACD Labs’ commercial modelingsoftware.Now in its 12 thversion, it conta ins most (but not all) of the features of commercial drawingpackages like ChemDraw, including “tools for 2D structure cleaning, 3Doptimization and viewing, InChiI generation andconversion, drawing of polymers, organometallics, Markush structures, and IUPACsystematic naming capability for molecules with fewer than 50 atoms and 3rings” (allowing ACD Labs to blow their own horn a little).A 2009 review concludes that ChemSketch andChemDraw are the top two drawing programs available (and only ChemSketch is free to students). Later on, more developers came to aid for development and code maintenance. Its originally written by Thomas Volk from Germany. Chemtool is a lightweight application for drawing chemical structures like organic molecules.

Recommended: ChemSketch 12 by Advanced Chemistry Development Laboratories (ACD Labs). Chemtool: Open-source Chemical Structure drawing program. A good program should provide an intuitive GUI interface, a variety of drawing tools and templates, control over the graphical details, and the ability to export the results in a variety of file formats as well as via the clipboard. Purpose: Everyone needs structure drawing software to create graphics of molecular structures and export them into papers, spreadsheets, websites, etc. ChemDoodle 2D has thousands of chemistry features that will help you create the best graphics possible and save you hours of work.
