Short history

January 2009 ''Original service launched'' :The service was launched with the brand name chemicalize.org. The main purpose was to identify chemical names on websites, but other services were also provided, such as property predictions and chemical search. August 2010 ''ChemSpider integration'' :Predicted chemical properties provided by Chemicalize were integrated to

ChemSpider ChemSpider is a freely accessible online chemical database, database of chemicals owned by the Royal Society of Chemistry. It contains information on more than 100 million molecules from over 270 data sources, each of them receiving a unique ...

. ChemSpider record pages contain links to access predicted properties on Chemicalize for the considered structure. September 2016 ''Renewed version'' :The platform was renewed using a new brand name Chemicalize. The new version offers enriched functionality in freemium model. May 2018 ''Chemicalize Professional released'' :Embeddable web components and hosted cheminformatics services, for web developers and integrators, based on Chemicalize cloud infrastructure.
