ALERT: Due to the COVID pandemic, CAS has lifted IP address restrictions until October 18, and logging in via UT's proxy server is not required at present. You still need your personal SciFinder ID and password.
Individuals affiliated with UT-Austin may register for a personal SciFinder account and use it from any computer that is connected to or proxied through the campus network, including library workstations. Authorized persons include:
These types of individuals are not allowed to register for or use SciFinder:
If you're new to UT but used SciFinder at a previous institution, your old account won't work here. Create a new one by registering above with your utexas.edu email address. TIP: If your web browser "remembers" and automatically enters your old SciFinder login ID and password, you'll have to clear that out and update it with your new one.
To get to all our licensed resources while outside the campus network, you must use our Proxy Server to establish a session that carries a recognized UT Austin IP address. To do this follow a link from any Library web page or database directory, and enter your UT EID and password when prompted. [Note: CAS has temporarily lifted IP restrictions due to COVID until October 18, 2020, and a proxy connection is not required at present.]
VPN will not work for this purpose, and will interfere with a proxy connection. Exit VPN and proceed through your existing network to establish a proxied connection via links on the Libraries' pages.
SciFinder is the best place to start your search for research-level chemical information. It provides integrated, user-friendly web access to these Chemical Abstracts Service (CAS) databases, plus Medline:
Note that UT does not subscribe to two additional data components within SciFinder, PatentPak and ChemZent.
SciFinder and Reaxys (incorporating Beilstein and Gmelin) are complementary resources, and although there is some overlap the two are quite different in their respective literature coverage, and the ways they register compounds and index reactions. It's advisable to consult both databases for the most complete coverage of compounds, reactions, and properties.
CAS has temporarily lifted the IP address restrictions during the pandemic work-from-home period, until October 18, 2020. This means that you don't need to log in via the Libraries proxy server, but you will still need your SciFinder ID and password.
CAS is currently rolling out a new SciFinder interface called SciFindern (yes, that's a superscript "n"). The "classic" SciFinder Web interface is no longer being developed with enhancements or new datasets, although the bibliographic, substance and reaction files are fully up to date. There is no retirement date for the classic version at this time. At some point in the future it's likely that UT System will have to migrate to the new version, but we have no firm plans to do so at this time.
