Database Information: (Note - the SciFindern interface is significantly different from the SciFinder interface, and may require practice for effective use even by experienced SciFinder users.)
SciFindern provides user friendly interfaces for searching by author, topic or chemical substance in the Chemical Abstracts Service databases:
- Over 40 million document records of the CAPLUS file, from 1907 to present, and selected records from before 1907, covering journal articles, patents, conference papers, technical reports, dissertations and more.
- Over 156 million substance records of the CAS REGISTRY file (over 91 million organic and inorganic "small molecules" and over 62 million polypeptide and polynucleotide sequences), with links to commercial availability information and regulatory information for many substances, and an ever-growing array of calculated and experimental property data for many substances.
- Over 77 million single and multi-step organic reaction records of the CASREACT file. It also includes detailed reaction information from MehotdsNow for selected reactions.
- Over one million searchable Markush structures from the chemical patents of the MARPAT file.
- Many patents are linked to PatentPak full text, with internal links to help you find specific chemical substances in lengthy patents.
- It also searches the MEDLINE database of over 28 million records from the world's biomedical literature.
SciFindern includes structure drawing tools for structure and substructure searching of chemicals and reactions, and similarity searching of organic compounds.
It also provides a Retrosynthetic Plan tool to help you create syhthetic paths to a desired substance.
