ACD/ChemSketch

ACD/ChemSketch is a chemically intelligent drawing interface that allows you to draw almost any chemical structure including organics, organometallics, polymers, and Markush structures. Following is the six highlights of this software :

1. Draw structures, reactions, and schema (e.g., biotransformation maps)
2. Generate IUPAC systematic names for molecules of up to 50 atoms and 3 ring structures
3. Predict molecular properties for individual structures (molecular weight, formula weight, density, logP, etc.)
4. Search for structures in the built-in dictionary of over 170,000 systematic, trivial, and trade names
5. Create professional reports, working with structures, text, and graphics simultaneously
6. Import and export structure files in a variety of standard file formats

 

 

Graph - Plotting of mathematical functions

Graph is an open source application used to draw mathematical graphs in a coordinate system. Anyone who wants to draw graphs of functions will find this program useful. The program makes it very easy to visualize a function and paste it into another program. It is also possible to do some mathematical calculations on the functions.
