SciFinder indexes millions of documents (from the late 19th century up to last week) that may contain desired physical property information. It's the best index to start this kind of search, but it helps if you first understand the database's scope, structure, and limitations, and learn some handy tips to get better results.

When you use a chemical name instead of a RN, SciFinder tries to resolve the RN automatically if it can. This can be less precise than using a predetermined RN, but also helpful.
You can also start a search from the "Explore Substances" option. This search does essentially the same thing as above but with one extra step. First, you search for a substance by Registry Number, molecular formula, name, or structure.
When you've identified the correct substance record, click the Get References link.
The Registry database in SciFinder also contains some experimental and predicted properties for substances (red arrow). Since we're talking about literature searching here, we'll pass over that option.
You'll see a pop-up menu of substance "roles." It's better NOT to select "Properties" here, for two reasons: 1) using it will retrieve only post-1967 references, since the Properties role has not been retrospectively assigned to RNs before that date; and 2) the Properties role is only assigned to RNs where property data are a primary focus of the report, meaning you'll miss documents where useful data are present but are more incidental to the topic.
From the list of references, you can then use the Refine tab to limit the results set using a property name.
When you use this method, "closely associated" proximity is not considered. This makes this method a bit less precise than the References search option shown in the previous tab.
