Chemistry Research Guide: Internet Resources

A collection of Cutting-Edge Interactive Databases and Dictionaries.

ChemSpider is a free chemical structure database providing fast text and structure search access to over 100 million structures from hundreds of data sources.

NCBI (National Center for Biotechnology Information) includes searchable databases containing nucleotide and protein sequences and protein structures.

This site provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data Program.

PubChem is the world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.

The PubChem Compound Database contains validated chemical depiction information provided to describe substances in PubChem Substance. Structures stored within PubChem Compounds are pre-clustered and cross-referenced by identity and similarity groups.

The PubChem Substance Database contains descriptions of samples, from a variety of sources, and links to biological screening results that are available in PubChem BioAssay. If the chemical contents of a sample are known, the description includes links to PubChem Compound.

Free database of chemical spectra. IR, MS, NMR spectra. Organized by National Institute of Advanced Industrial Science and Technology (AIST), Japan.

This site contains the reference sequence and working draft assemblies for a large collection of genomes. It also provides portals to ENCODE data at UCSC (2003 to 2012)

This database lets you access 154 years of patent descriptions and images. You can search, retrieve and study more than 2,530,000 patent documents.

Patent office for Europe

Covers patents and applications from USPTO, EPO, WIPO and JPL abstracts

Covers patents and applications from USPTO, EPO, WIPO, DPMA, CIPO and SIPO.

A searchable database of Japanese patent abstracts, which includes the patent number, title, inventor, company, and abstract of the patent.

Search, analyze and manage patent data and only database with genetic data

The Patent Public Search tool is a new web-based patent search application that will replace internal legacy search tools PubEast and PubWest and external legacy search tools PatFT and AppFT. Patent Public Search has two user selectable modern interfaces that provide enhanced access to prior art. The new, powerful, and flexible capabilities of the application will improve the overall patent searching process.

WIPO search engine: Patentscope. Search International and National Patent Collections.
