Open Source MinGW/MSYS2 Chemistry Software

OSRA is a utility designed to convert graphical representations of chemical structures and reactions, as they appear in journal articles, patent documents, textbooks, trade magazines etc., into SMILES or SD file format- a computer recognizable molecular structure You can find links to the binary executables here: https://sourceforge.net/p/osra/wiki/Download/

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

GParticles is a tool to simulate the growth behaviour of two- and three-dimensional nano particles based on a simple grid model, with adjustable (time-dependent) concentrations of the particle's different components.

A library for reading Mass Spectometry files. Reuse mzXML converter code but compile with gcc and Qt instead of MSVC. Some features have been added, e.g. UV scan reading

NMR-Ghost a tool for analyisis and visualization of in-vivo NMR spectroscopic data

Periodic Table of Elements is a quick reference tool that allows you a quick glance to get general information about an element. The program is for educational purposes.

An editor for small organic molecules, written in C using gtk+. It can read and write SMILES and cml and can save to dia's file format. It is suitable for creating chemical molecule diagrams for lower level chemistry/ochem lab reports.

We've moved to https://github.com/tjod/gMol/wiki gMol is an interactive visualization system used to display and manipulate 3-dimensional models of scientific data, such as molecular structures and surfaces. It contains both OpenGL and web browser widgets that enable flexible user interfaces.

ISL Equilibrium Calculator,which process solid-liquid equilibrium calculation by using Harvie extended Pitzer's ion interaction electrolyte solution model and particle swarm optimization Gibbs free energy minimization (GEM). ISLEC is an efficient tool for solid-liquid equilibrium calculation, and can simulate the crystallization path of seawater and salt lake brines. ISLEC is suitable for related researches and process design.

Command line molar mass calculator that provides typo checking and options for printing elemental analysis and saving a record of previously calculated molar masses.

spclib provides a free and open library for the manipulation of spectral files in the Grams SPC format
