Chemistry Lab Resources (for CHM 1XX and 2XX Labs)

Here you can find tips about organizing your lab notebook, how to effectively create graphs and table for lab reports, places to locate protocols and property information, and how to properly cite resources.

Searching for a compound

There are many ways you can describe a compound in order to search for it within a database.  Consider your options and what types of descriptions the particular database will accept.  If you get zero results, try another way before moving on to another resource.

Chemical name/synonyms
Common/trivial name
Molecular formula
Empirical formula
CAS Registry Number

For example, consider ethanol:

ethyl alcohol
ethyl hydroxide
CAS# 64-17-15

Additional Property Sources

Organic Synthesis Resources

Start with these online resources

These resources collect information on the most commonly encountered compounds and their most basic properties. If you are not finding an entry under the first chemical name that you try, try another synonym for that same compound or in the case of some of the sources, draw the structure of the compound you are looking for.  Then try one of the more comprehensive sources (other tabs) or contact Jeremy (contact info on the right) if you are still having trouble finding the data you need.

And what about Wikipedia and Wolfram Alpha?

Both Wikipedia and Wolfram Alpha can be quick and easy to seach when it come to chemical and physical properties.  But before you use these resources, please consider the following when searching each source.
