ChemicalScan is an online reference resource that makes European Union chemical safety data more accessible. It brings information sourced from the European Chemicals Agency (ECHA) into searchable substance profiles, helping researchers, students, and safety professionals find and understand relevant classifications and regulatory details. The database covers more than 106,000 substances, searchable by name, CAS number, or EC number. Profiles present substance identifiers, hazard classifications, GHS pictograms, and EU regulatory status.

Users can browse lists of Substances of Very High Concern, REACH Authorisation List substances, and substances subject to restrictions, as well as explore hazard statements, pictograms, and an alphabetical index. ChemicalScan also offers plain-language guides to REACH, the CLP Regulation, and the Globally Harmonized System, alongside articles on chemical safety and regulation. Its purpose is to help users interpret complex chemical information and see which substances face EU regulatory scrutiny. ChemicalScan states that its data comes from ECHA and that it is not affiliated with ECHA; the information is provided for reference only.
