GChemPaint is a 2D chemical structures editor for the Gnome-2 desktop. It is a two dimensional chemical structure editor for Linux Operating System. It is free and open source software(FOSS) developed in 'C'. It is useful for students, teachers and teacher educators, researchers. GChempaint was developed by Jean Bréfort in 2001. For details visit http://www.nongnu.org/gchempaint/

GChemPaint allows to draw and display two dimensional chemical structures. It has inbuilt templates with different categories of structures that can be loaded into the GChemPaint Display area. It has an inbuilt Modern periodic table. It supports multiple file formats like .mol, .pdb .svg, .pdf and other forms. It has an inbuilt Chemical Calculator to calculate molecular weight of compounds and view mass spectra. It helps to convert drawn 2D structures to 3D structures using GChem3D feature. Structures can be viewed in "ball and sticks", "space filling", "Cylinders" and "wireframe". Periodic table trends and properties can be shown using the GChemTable feature. Different types of charts can be created and viewed using GChemTable.
