Finding Full Text from SciFinder-n

To locate full-text articles click on the link to Full Text in SciFinder-n  (use the Library Access button in other databases).  To access these resources off-campus use your UMNetID and Password.  Then select Check Library Access. If you select DOI you will need to install the Library Access Browser extension in order to access resources that are paid for by the Libraries.

Searching for Property Data in Journal Articles

If you can’t locate the information you need in the Starting Sources section try searching the SciFinder database for journal articles.  Select the Substance Identifier search and enter the CAS Registry Number. 

Check out the video below on how to use SciFinder to locate physical property data.  Using the Substance Identifier search option you can also enter the CAS Registry number. SciFinder will list journal articles that have melting points under the Key Physical Properties link.  

Additional journal articles might also be found by clicking on the Get References option and selecting Preparation or Properties.  You will probably need to look at the journal article to see if the melting point is listed in the article.

Other options to find property data like melting points in a journal article include looking at the references that are included in one of the starting sources for physical property information.
 
 

Search Options

Finding chemical property data when you only have a chemical name is very difficult in organic chemistry, especially for complex names. Many compounds have more than one name as well.   Some compounds, like esters, can even be named with the parent acid name followed by the type of ester.  Eg.  butanoic acid, propyl ester.

Simple names or trade names work best.  If you cannot find information using a chemical name try other search options like a chemical structure search or searching by CAS Registry Number.

CAS Registry Numbers (Chemistry Abstracts Registry Numbers) are the preferred way to find information on a particular chemical compound in any online database or online handbook.  CAS Registry Numbers look like  28994-41-4  or 2550-36-9 or 110-82-7.  The first segment can be from two to seven digits long.  If you can't locate a registry number you can also try searching by molecular formula or chemical structure.

If you only have a chemical name, try a Google search for the chemical name to see if you can find a Chemical Abstracts Registry Number for the chemical.  Registry numbers are often located on chemical supplier webpages or MSDS sheets.  Look for CAS Reg#, CAS RN or RN followed by the registry number. 

Go to the Starting Sources for Physical Data and try searching by the CAS Registry Number.  In some cases you will have to find a search option that allows you to search by CAS number.  Some search examples are listed below:

  • CRC Handbook of Chemistry and Physics – click on Structure/Property Search  and then enter the CAS Registry Number in the CAS Registry No. search box.
  • Merck Index – Enter the Registry Number in the default search box.
  • Combined Chemical Dictionary – Enter the Registry Number in the CAS Registry Nos. search box.
