XDrawChem is a program for drawing chemical structures. Features include fixed length and fixed angle drawing, a ring tool to automatically draw rings, automatic alignment of structures in reactions, 2D structure diagram generation, and 3D structure conversion. It can access structures in the PubChem compound database by name, CAS number, or formula. It can output InChI for structures and search the database by structure. It can predict 1H NMR, 13C NMR, simple IR spectra, and estimated pKa. XDrawChem can work with its native file format, ChemDraw files, and any format supported by OpenBabel (MDL Molfile, CML, etc.).
GenChemLab is an OpenGL-based application intended to simulate several common general chemistry laboratory exercises. It is meant to be used to help students prepare for actual lab experience. Supported experiments include titration, calorimetry, freezing point depression, vapor pressure, electrochemistry, and spectrophotometry.
