ACD/ChemSketch Freeware is a drawing package that allows you to draw chemical structures including organics, organometallics, polymers, and Markush structures. It also includes features such as calculation of molecular properties (e.g., molecular weight, density, molar refractivity etc.), 2D and 3D structure cleaning and viewing, functionality for naming structures (fewer than 50 atoms and 3 rings), and prediction of logP.
ACD/Labs software aids in teaching key chemistry concepts to high .....
ArgusLab is a molecular modeling, graphics, and drug design program for Windows operating systems. It’s getting a little dated by now, but remains surprisingly popular. To date, there are > 20,000 downloads.
Scientists have discovered that thanks to computer programs they can advance in their projects a lot faster, due to the fact that they can speed up the calculations that would have previously taken weeks of work. In the case of chemistry, we have to highlight the .....

Scintilla is a free source code editing component. It comes with complete source code and a license that permits use in any free project or commercial product.
As well as features found in standard text editing components, Scintilla includes features especially useful when editing and debugging source code. These include support for syntax styling, error indicators, code completion and call tips. The selection margin can contain markers like those used in debuggers to indicate breakpoints .....
SciTE is a SCIntilla based Text Editor. Originally built to demonstrate Scintilla, it has grown to be a generally useful editor with facilities for building and running programs. It is best used for jobs with simple configurations - most use it for building test and demonstration programs as well as SciTE and Scintilla.
Text editing in SciTE works similarly to most Macintosh or Windows editors with the added feature of automatic syntax styling. SciTE can hold multiple files in memory at o .....
