User Q&A

Streamlining Your Workflow by Utilizing DISPLAY BROWSE and TAG Commands in STN Express

Q. When browsing through my STN Express search results, I typically jot down the numbers of the records I am most interested. Rather than using pencil and paper, can I electronically label my records of interest?

A. Yes! Here’s a sample search that shows how to use DISPLAY BROWSE to scan the records in your answer set. Then use the TAG command to indicate records that are most relevant to your needs. For our example, we will use a search for new techniques to detect adulteration of wine, and to authenticate wine.


Let's review some records from L3 and identify those most relevant to the search question. DISPLAY BROWSE provides the default display format for your database (in this case, BIB) unless you indicate otherwise. Enter TAG at the prompt to identify record 1 as relevant.

Analyzing Variability in Structure Related Substances Using R-group Analysis Table Tool

Do you have an answer set of structurally related substances for which you would like to determine the common structure and summarize the variability that occurs at specific nodes? We have just the tool for you!

The R-group (Variable Group) Analysis Table Tool in STN Express allows you to create a substance analysis table based on a common substructure. Simply identify the nodes on your substructure where you would like to see the range of substitutions that occur in a collection of CAS REGISTRYSM substances. A simple R-group table is shown here. Keep in mind that multiple R-groups can be summarized in your table.

To learn more about the R-group Analysis Table Tool, refer to the STN Express User Guide.

Science IP

abcdScience IP, the CAS Search Service, contributes monthly articles describing best practices and useful information from real searches. This month's article takes a look at the basics of MARPAT® on STN.

STN provides access to a variety of structure searchable chemical databases, including exemplified compound databases (e.g., CAS REGISTRY), reaction searchable databases (e.g., CASREACT®) and the CAS Markush database, MARPAT. In MARPAT, searches often retrieve relevant patents which are not found by searching exemplified compound databases. This valuable data may be critical for searches relating to freedom to operate, patentability and validity questions. Read more here.
