ACD/ChemSketch is an advanced chemical drawing tool and is the accepted interface into the industry's best NMR and molecular property predictions, nomenclature, and analytical data handling software.
ACD/ChemSketch is also available as freeware, with functionalities that are highly competitive with other popular commercial software packages. The freeware contains tools for tautomer prediction, 2D structure cleaning, 3D optimization and viewing, drawing of polymers, organometallics, and Markush structures - capabilties which are not even included in some of the commercial packages from other software producers. Also included is an IUPAC systematic naming capability for molecules with fewer than 50 atoms and 3 rings. The capabilities of ACD/ChemSketch can be further extended and customized by programming.
