A Free Comprehensive Chemical Drawing PackageACD/ChemSketch Freeware is a drawing package that allows you to draw chemical structures including organics, organometallics, polymers, and Markush structures. It also includes features such as calculation of molecular properties (e.g., molecular weight, density, molar refractivity etc.), 2D and 3D structure cleaning and viewing, functionality for naming structures (fewer than 50 atoms and 3 rings), and prediction of log P. The freeware version of ChemSketch does not include all of the functionality of the commercial version —.

FunctionalityCommercialFreewareAdvanced drawing tools✓✓Identify tautomers✓✓Name structures with up to 50 heavy atoms✓✓3D viewer✓✓Export to Adobe PDF✓✓ACD/Dictionary✓Search files on your computer by structure✓ACD/Labs extension for ChemDraw✓Technical Support✓× As an Educational ToolACD/Labs software aids in teaching key chemistry concepts to high school, undergraduate, and graduate chemistry students. In addition, students benefit from exposure in the learning environment to the same tools they will encounter in the workforce. Our Academic Site Licensing Program is a convenient way for qualifying academic institutions to make the freeware version of ACD/ChemSketch available to their students and faculty. Free access to site licenses of ACD/ChemSketch Freeware are available. To learn more.
