Summary
Abstract: ChemIDplus is a free, web-based search system that provides access to
structure and nomenclature authority files used for the identification
of chemical substances cited in National Library of Medicine (NLM)
databases. ChemIDplus also provides structure searching and direct
links to many biomedical resources at NLM and on the Internet for
chemicals of interest. The database contains over 350,000 chemical
records, of which over 80,000 include chemical structures, and is
searchable by Name, Synonym, CAS Registry Number, Molecular Formula,
Classification Code, Locator Code, and Structure.

To use ChemIDplus, you will need a web browser that provides the
capabilities needed to accept a structure query into the Chime plug-in
which allows you to view the structures. A compatible structure
drawing package such as ISIS/Draw will allow custom structure queries
to be drawn. Without the plug-in, the search system will not display
the structure but will still search and display all text data
(e.g. Name, Synonym, CAS Registry Number, Molecular Formula,
Classification Code, and Locator Code).

The Locator Codes are hyperlinked at the substance level to biomedical
databases at NLM and on the Internet and to the SuperList compilation
of chemical substances of interest to Federal and state regulatory
agencies. Ease of navigation from the Locator Display Page to these
other Web sites and vice versa is a characteristic feature of
ChemIDplus.

For advanced searchers, there are three types of structure queries:
Substructure Search, Similarity Search, and Exact Structure
Search. ChemIDplus facilitates structure searching by providing two
options that eliminate the need to draw the structure queries. One
option, Use Structure for Query, pastes the retrieved structure from a
previous query to the Structure Input Box while the other option, Use
Structure for Similarity, starts an immediate search for similar
structures.
