ACD/ChemSketch Freeware

The latest version lets users quickly and easily draw all kinds of chemical structures including polymers, organometallics, and Markush structures, optimize spatial configuration, and view structures in 2D or 3D. Generate IUPAC and CAS Index nomenclature for molecules with fewer than 50 atoms and 3 ring structures, and get predictions of the octanol-water partition coefficient, logP, along with other molecular descriptors. Access to ACD/I-Lab, our pay-per-use online engine for the prediction of physicochemical, ADME, and toxicity properties, NMR spectra and chemical shifts, and chemical names, is also provided.
