XDrawChem is a free software program for drawing chemical structural formulas, available for Unix and macOS. It is distributed under the GNU GPL. In Microsoft Windows this program is called WinDrawChem.{{cite journal |last1=Gupta |first1=Monika |title=Ict Tools for Teaching and Research in Chemistry |journal=International Research Journal of Modernization in Engineering Technology and Science |date=2023 |volume=5 |issue=1 |doi=10.56726/IRJMETS32852}}

Major features

  • Fixed length and fixed angle drawing
  • Automatic alignment of figures
  • Detection of structures, text, and arrows, and their automatic placement
  • Can automatically draw rings and other structures - has all standard amino acids and nucleic acids in a built-in library
  • Retrieval of structures from a network database based on CAS number, formula, or name
  • Retrieval of information on a molecule based on a drawing
  • Symbols such as partial charge and radicals
  • Reading MDL Molfiles, CML (Chemical Markup Language), ChemDraw binary format, ChemDraw XML text format{{cite journal |title=Review of bioinformatic tools used in Computer Aided Drug Design (CADD) |journal=World Journal of Advanced Research and Reviews |date=30 May 2022 |volume=14 |issue=2 |pages=453–465 |doi=10.30574/wjarr.2022.14.2.0394|doi-access=free |last1=Namitha k n |last2=v Velmurugan }}
  • Writing MDL Molfiles, CML, ChemDraw XML text format
  • Integration with OpenBabel, allowing XDrawChem to read and write over 20 different chemical file formats.
  • Image export in Portable Network Graphics (PNG), Windows bitmap, Encapsulated PostScript (EPS), and Scalable Vector Graphics (SVG)
  • 3D structure generation with the help of the external program BUILD3D
  • Simple spectra predictions, including 13C-NMR, 1H-NMR (based on additive rules and functional group lookup methods), and IR{{cite journal |last1=Winkler |first1=David |title=Free software for chemistry |journal=Chemistry in Australia |date=2017-09-01 |pages=24–27 |url=https://search.informit.org/doi/10.3316/informit.146690140751271 }}
  • Simple property estimation, including pKa, octanol-water partition coefficient, and gas-phase enthalpy change.
