馃К Chemistry structure drawing software 鈿ree! Easy to use 馃帗 For researchers, students, and educators

Joined September 2025
4 issues are fixed in moldraw. 1) Bond tool + oxygen 聽 Clicking a bond now changes the bond order only. It no longer turns an atom into oxygen (or another element) when an element is selected in the sidebar. Atoms change only when you click the atom. 2) Eraser drag box 聽 With the eraser tool, left-click and drag on empty canvas draws a box and erases the atoms/bonds inside. Single-click erase still works. 3) Lonely unlabeled carbon 聽 If you erase one carbon from a two-carbon molecule, the remaining carbon stays visible and labeled as聽C, so you can find and edit it. 4) Chiral molecule naming 聽 One wedge or dash on a stereocenter is enough for the name to appear in molecule info. You no longer need two stereo bonds.

Thanks Rade :) Version 2 will be much better. Current version has some limitations. Major ones are already solved in version 2!
I just discovered @moldraw. Pretty happy with it thus far.
