Using Reaxys for the CH224 literature searching lab assignment

About Reaxys

Reaxys is an incredibly robust chemistry database that could be used to complete the entire lab assignment (or do any chemistry research, for that matter). Not that you necessary should--its interface is complex compared to most reference soures listed in the lab manual or on the main CH224 page, and those sources will be fine. It's important to professional chemistry researchers and any students planning further chemistry studies should learn to use it. It's very helpful for locating information on substances, articles about any chemistry topic, structures, and reactions.

Access to Reaxys

Reaxys is available through the NCSU Libraries. Like most library databases, accessing it through the Libraries' website provides easy access on- or off-campus. Users can create individual accounts within the database interface (not tied to NCSU Unity accounts) to save searches or create alerts.

Using Reaxys

For the literaure search assignment, you don't need to learn everything there is to know about Reaxys. There are essentially two search options, accessible via the start screen.

  1. Structure searching – Search for chemical information by structure. Useful in organic chemistry, but not necessary for the literature searching assignment.
  2. Property searching – Search by other properties such as CAS number or name, or more advanced searching by multiple properties (e.g., find all chemicals with a melting point above 5000 with available NMR spectroscopy data).

Physical Properties

Use the Property Searching forms. CAS number is most concise and uniquely identifies a substance. CAS number is the most concise search and uniquely identifies a substance. Common names often work, but may not be precise.

To search for a compound:

  • Make sure the Substances and Properties tab is selected.
  • In the Properties (Form-based) tab, expand "Substance Data".
  • Expand "Identification Data".
  • Type the CAS number into the box labeled "CAS Registry number". The form provides an autocomplete function to help find values.
  • Click Search.

In your search results, check under Available Data. Physical Data should be highlighted. Click to see what is available. (Screenshot)

Hazardous Properties and Spectra

This type of data is not the strength of Reaxys, but can be available. Locate your compound as described in the Physical Properties section. Check the Available Data to see if there is anything noted pertaining to "Bioactivity/Ecotox" or some other physiologically-relevant property. If there is any information available Reaxys will provide some description and a reference to the source of the information. Click the Full Text or FindText@NCSU link to locate the source article.


See the main synthesis page to see how to use Reaxys to find this information.
