Finding Molecules With eMolecules
February 24th, 2008 | Published in Academic, tools | 2 Comments
eMolecules searches the Internet for chemistry-related information — more specifically, information about molecules.
You can draw a molecule or molecule substructure – using a popup Java applet. Once you’ve drawn the molecule, eMolecules “translates” your drawing to a search engine query.
We know – this is kind of geeky. But don’t you agree it’s pretty cool?
If you want to do text-based searching, you can do that too. Even by trade name.
Here is Advil. Who would have thought?


You might be interested in ChemSpider also. eMolecules is about 8 million compounds while ChemSpider is approaching 20 million compounds.
You can search by text, chemical property, structure or substructure. An overview of the site is given here:

The advantages of this site are many fold but includes user-curation of the data, the ability to upload new structures to the site and the presence of analytical data on the site also.
The Blog describes a lot of what we do: http://www.chemspider.com/blog/
Best wishes.
Thanks for the info! We’re always looking for new resources.
