SciFinder is produced by the Chemical Abstracts Service (CAS) under the American Chemical Society (ACS). When CAS was founded in 1907, the product was the paper "Chemical Abstracts". In 1995, it began to provide scientific researchers with an online access database platform: SciFinder. In terms of content, in addition to the complete coverage of all paper "Chemical Abstracts", SciFinder also includes substance databases, chemical reaction databases, chemical online, and compound compliance control information. In terms of function, SciFinder provides multiple retrieval methods and multiple post-processing functions.
Overall collection: SciFinder is a powerful search and analysis tool, through SciFinder you can access the world's largest collection of chemical information. The database contains documents from more than 180 countries, with a total of more than 50 thousand journals and nearly 10 thousand journals. In addition to periodicals, patents from global patent licensing agencies are also included. The literature dated to the beginning of the 19th century.
SciFinder can access contents from the following databases: CAS REGISTRY， CAplus, CASREACT, CHEMLIST, CHEMCATS, MARPAT, MEDLINE, PatentPak and MethodsNow.
Introduction of PatentPak
PatentPak is a patent process solution for researchers and intellectual property-related workers, providing more than 18 million patent PDF full texts from 46 patent licensing agencies around the world (continuously adding newly published patents), patent families, reading analysis Tools etc. PatenPak can save researchers more than half of the time in locating and analyzing the large number of chemical, biological substances disclosed in the patent. PatentPak is the most reliable tool for accelerating chemical patent analysis. So far, only PatentPak uses manual indexing, which can quickly identify substances that are difficult to find in patents for researchers (such as tabular compounds, compounds represented only by name or development code, etc.). Use PatentPak to seamlessly link to CAS REGISTRYSM, the world's largest collection of substance information in SciFinder. PatentPak has been integrated into SciFinder, and PatentPak can be used when using SciFinder.
Introduction of MethodsNow
Analysis method: https://www.methodsnow.com (using SciFinder account, IP authentication + account registration access, no concurrency limit)
Synthesis method: https://scifinder.cas.org/
MethodsNow is the world's largest collection of analysis and synthesis methods. The analytical method part is an independent product platform, covering pharmacology, toxicology, food science, natural product analysis, agricultural analysis, biological analysis methods, fuel/geology/biofuel, organic compound analysis, metal organic/inorganic compounds and water quality analysis. The synthetic method module is embedded on SciFinder, providing detailed analysis methods and synthetic method operation steps. MethodsNow collects nearly 5 million synthesis reactions from the world's top English journals and patents; at the same time, it collects nearly 500 thousand analysis method-related documents from more than 4,000 journals. The main features include: covering synthetic preparation information in top journals and patents; a retrieval function that is easier to obtain information created by CAS scientists; easy access to millions of publicly disclosed method details, saving a lot of time; easy-to-read tables showing experimental details in the form; including experimental materials, instruments, experimental conditions and other information; rapid step-by-step comparison of analysis methods, etc. MethodsNow Synthesis has been integrated into the SciFinder platform. Use the SciFinder account to log in to www.methodsNow.com to use MethodsNow Analysis.
The CAS database includes: more than 142 million organic and inorganic chemical substances, more than 67 million sequences, more than 47 million documents, 106 million reactions ( more than 90 million single-step and multi-step reactions, more than 14.2 million Synthetic preparation information), more than 388,000 substance list controlled chemicals, millions of chemicals from hundreds of commercial chemical suppliers around the world, more than 1.1 million searchable Markush structures, more than 12 million patents (until 2015.9.18).
Subjects included: applied chemistry, chemical engineering, general chemistry, physics, biology, life science, medicine, macromolecules, materials science, geology, food science, agronomy and many other fields.
