SciFinder-n: What Is SciFinder?

SciFinder, produced by Chemical Abstracts Service (CAS), is the most comprehensive database for the chemical literature, searchable by topic, author, substances by name or CAS Registry Number, OR use the editor to draw chemical structures, substructures, or reactions. It's a core research tool for chemistry, biochemistry, chemical engineering, materials science, nanotechnology, physics, environmental science and other science and engineering disciplines. Depending on your research, SciFinder is complementary to other databases like ReaxysWeb of SciencePubMedCompendex and INSPEC.

- CAS Registry -

52+ million references from thousands of journals and patents, as well as technical reports, books, conference proceedings, and dissertations. Continuous coverage back to 1907, with selected coverage before that.

SciFinder also includes the Medline database of 25 million references to the biomedical literature (you can eliminate the duplicate Medline references).

161+ million organic and inorganic substances, many with associated experimental and predicted property data.

Substances can be searched by name, CAS Registry Number, or through a structure or substructure search using the editor.

126+ million single- and multi-step reactions and synthetic preparations, from 1840 to date. Many with yield data, detailed reaction conditions, and experimental procedures.

Reactions can be drawn in the structure editor and searched, or retrieved from a substance record from the CAS Registry.

Commercially available chemicals, drawn from hundreds of supplier catalogs, with information on pricing and availability.

Regulatory information on 389,000 chemical substances, from 150 regulatory inventories and lists.

1.2+ million searchable Markush representations from 500,000 patents.
