About SciFinder

SciFinder is the premier research discovery tool for pure and applied chemistry. It has an index of chemical structures and reactions, as well as bibliographic information from a broad base of scientific literature, including conference articles, dissertations, patents, and more. SciFinder includes millions of citations from 1907 to present, in the fields of chemistry, biomedical sciences, agricultural science, materials science, and other related fields.

Users can search by topic, author, registry numbers, and more. Substance data includes properties, known structures, chemical names and formulas, CAS Registry numbers, roles, and chemical suppliers.

SciFinder is co-searchable with Medline.
