Help: Chemical and Physical Properties

To more quickly find your specific information, try using the HELP: online chemistry librarian emulator to idenitify the most appropriate information resources by property.

Recommended Resources:
The tools listed below are easy to use, easy to find and contain reliable information. Although each tool has its own merits, there is a lot of overlap in the types of compounds and information covered. The information compiled is often taken from larger resources like the Beilstein/Gmelin database. Because of the overlap in information, if you cannot find the information you are looking for in one of these handbooks it is better to move to a larger, more in-depth resource (like the Dictionary of Organic Compounds or the Beilstein/Gmelin Crossfire database) than it is to check in the rest of these handbooks.
