ChemPencil

ChemPencil is a powerful and easy to use Mac App for drawing organic molecules. ChemPencil tools and features include: • Draw bonds and molecules in ACS standardized style. • Label heteroatoms directly in the drawing without losing sight of your document. • Add common abbreviations to atom’s labels. • Heteroatom’s labels rearrange conveniently when rotating the molecule. • Represent bond stereochemistry with hashed and bold bond type. • Ring building tools to draw aromatic and aliphatic rings. • Add text to the document for example for naming a molecules or naming a reaction scheme. • Export or email your document as a PDF. • Select and copy molecules in ChemPencil and paste them directly in your Keynote document. • Calculation and plot of isotopic distribution graph.
