Chemicalize is an online platform for chemical calculations, search, and text processing.[1] It is developed and owned by ChemAxon and offers various cheminformatics tools in freemium model: chemical property predictions, structure-based and text-based search, chemical text processing, and checking compounds with respect to national regulations of different countries.

Modules of ChemicalizeEdit


Chemical property predictions for any molecule structure. Available calculations include elemental analysis, names and identifiers (IUPAC name, SMILES, InChI), pKa, logP/logD, and solubility.[2]

Chemical Search

Structure-based and text-based search against the Chemicalize database to find web page sources and associated structures of the results.[3]

Compliance Checker

Checking compounds with respect to national regulations of several countries on narcotics, psychotropic drugs, explosives, hazardous materials, and toxic agents.

Short historyEdit

January 2009 Original service launched

The service was launched with the brand name 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.[4] 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.[5] 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.
