The latest version of the chemical drawing package ACD/ChemSketch Freeware (version 11.0) is available for download from the ACD/Labs website.
The ACD/ChemSketch Freeware package is available free for home or academic use and allows users to draw structures for any molecule including polymers, organometallics and Markush structures.
ChemSketch Freeware also features 2D structure cleaning, 3D viewing and optimisation, and an IUPAC naming function for molecules up to 50 atoms and 3 rings.
Version 11 has several new features built-in, including: interface changes, new shortcuts, and toolbar menus to streamline workflow; improvements in digital graphical representation, including a new ‘antialiasing’ option for chemical structures; combined styles for American Chemical Society (ACS) and Royal Society of Chemistry (RSC) journals to simplify the process of preparing publications; and improved handling of coordination structures for those working with inorganic compounds.
A commercial version of ACD/ChemSketch is also available, with more advanced functionality, including a dictionary of more than 158,000 common, trivial and trade names and their structures; the ability to view SDfiles; and a structure search functionality allowing you to seek out chemical structures of various file formats.
