ChemSketch 5.0 Freeware

The freeware version of ACD/ChemSketch provides chemical drawing capabilities, surpassing other popular commercial products. The freeware contains tools for tautomer prediction, 2D structure cleaning, and 3D optimization and viewing, capabilities 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 tools using an included Basic-type language, ACD/ChemBasic. The Freeware software is presently limited to version 5.0. Commercial ACD/ChemSketch is available as version 8.0.
