SciFinder is the most comprehensive chemical information discovery tool of chemical information. It is used to access information in selected Chemical Abstracts Service (CAS) databases: CAPlus, CARegistry, CAREACTS, CHEMCATS, and CHEMLISTS, plus the NIH database Medline.
SciFinder requires an individual username and password. Registration information is below. If you have an account with a previous institution, you must create a new account with your UW-Madison email address.
Note: This version will be retired by the CAS at the end of 2022. Users will then need to use SciFinder-n to search the Chemical Abstracts databases.
In addition to the content found in SciFinder, SciFinder-n includes relevance-ranked results, step-by-step procedures and protocols, citation mapping, biosequence searching, retrosynthetic analysis, patent landscape mapping, touch-screen enabled structure drawing and more—all accessible in a modern interface.
