ChemSpider is a web-based database of chemical data and links to related articles and patents. The range of data stored in ChemSpider includes chemical structures, identifiers (IUPAC/common/trade names, synonyms, SMILES, InChIs), properties (experimental and predicted), spectral, crystallographic, and images. The ChemSpider website is freely available resource developed for the scientific community which allows users to search, deposit and curate data. The data in ChemSpider has been supplied by various institutions and commercial companies.

Data in ChemSpider is curated on an ongoing basis by ChemSpider staff and users to ensure data integrity and data quality. ChemSpider has a wide user base which includes students, teachers, lecturers, scientists (chemists, biochemists, material, forensic, quality control, analysts), patent agents, publishers and chemical manufacturers.
