ChemWindow
ChemWindow is a chemical structure drawing molecule editor and publishing program now published by John Wiley & Sons as of 2020, originally developed by Bio-Rad Laboratories, Inc. It was first developed by SoftShell International in the 1990s. Bio-Rad acquired this technology in 1996 and eventually made it part of their KnowItAll software product line, offering a specific ChemWindow edition of their software for structure drawing and publishing. They have also incorporated ChemWindow structure drawing components into their KnowItAll spectroscopy software packages with their DrawIt, ReportIt, and MineIt tools.
