Marvin, which is free. If that doesn't suit you, our users have ranked 12 alternatives to ChemDraw and seven of them are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to ChemDraw are 
ChemDoodle (Paid), 
BKchem (Free, Open Source), 
XDrawChem (Free, Open Source) and 
JChemPaint (Free, Open Source).
Utility for processing, structuring, and drawing chemical data. If you're looking for more info about ChemDraw like screenshots, reviews and comments you should visit our info page about it. Below you find the best alternatives.
Marvin suite is a chemically intelligent desktop toolkit built to help you draw, edit, publish, render, import and export your chemical structures and as well as allowing you to convert between various chemical and graphical file formats. It is free for individual, academic and non-commercial use.
If you are looking for a chemical sketcher or an alternative to your current chemical drawing application, there is no better choice than ChemDoodle. ChemDoodle works on all operating systems (both 32 and 64 bit), has one of the largest feature sets in the industry, has the most customizable graphics, pastes scalable vector graphics into Microsoft Office, iWork and OpenOffice (among others), and can read and write all of our competitors’ formats.
BKChem is a free (as in free software :o) chemical drawing program. It was conceived and written by Beda Kosata and is currently maintained by Reinis Danne. BKChem is written in Python, an interpreted and very nice programming language. This implies some of the program features: * platform independence - BKChem should run on any platform that Python does.
XDrawChem is a free software program for drawing chemical structural formulas, available for Unix and Mac OS. It is distributed under the GNU GPL. In Microsoft Windows this program is called WinDrawChem.
JChemPaint is an editor and viewer for chemical structures in 2D. It is free and open source software, written in Java and so it runs on Windows, Mac OS X, Linux and Unix systems. There is a standalone application (editor), and two varieties of applet (editor and viewer) that can be integrated into web pages.JChemPaint is currently being developed as part of The Chemistry Development Kit, and a Standard Widget Toolkit-based JChemPaint application is being developed, as part of Bioclipse.
MollyCule is a completely free Open Source Chemistry visualisation program for MacOS, Linux and Windows. MollyCule is designed to be a nice, easy to use program to help ordinary people who want to explore Chemistry. It's probably not ideal for PhD researchers, but it's great for high school students and undergraduates. Traditionally, chemistry visualisation packages have used keyboards or complicated mouse-gesture systems.
The Gnome Chemistry Utils include six chemistry related programs: - GChemPaint, a 2D chemical formula editor. - a chemical calculator (computes raw formule, molar weight, mass composition and isotopic pattern). - a molecule 3d viewer using OpenGL to display molecular models. - a crystal structure editor and viewer. - a periodic table of the elements. - a spectrum viewer.
