ChemAxon (/ˌkɛmˈæksɒn/) is a cheminformatics and bioinformatics software development company specializing in cloud based, end user solutions, back end platforms and consultancy services for chemical and biological research.[1][2] Headquartered in Budapest, Hungary with 121 employees (as of November 2018).[3] The company also operates business and consultancy offices globally in Cambridge, MA, San Diego, CA, and in Prague.[4][5][6] ChemAxon supports its customers via exclusive distributors in China, India, Japan, South Korea, Singapore, and Australia.[7][8][9] ChemAxon provides solutions, platforms, applications, and consultancy services for handling chemical and biological entities for the pharmaceutical, biotechnology, new materials, fine-, petro- and agrochemical, food and cosmetics industries. ChemAxon supports academic institutions through special software licensing programs for students, teachers, academic researchers, and high school curriculums[10]. Tools and software solutions are offered to academic research groups wishing to integrate cheminformatic functionalities into open website platforms via web hosting services.[11][12]


ChemAxon Products include tools for visualization and drawing of molecules, chemical database searching and management, and for drug discovery. Products are licensed free of charge for academic use.[13]

ChemAxon’s desktop applications include Marvin which is a free chemistry software for drawing and visualizing chemical structures,

Instant JChem, a desktop application for end user scientists; JChem for Excel which integrates the structure handling capabilities of JChem and Marvin within a Microsoft Excel environment.[14]

The software can be used to predict pKa values[15] and logP values.[16]

The company developed Markush structure storage and search capabilities (without enumeration), with Markush structures from Thomson Reuters Derwent World Patents Index (DWPISM) database.[17]

Pearson Education uses ChemAxon's JChem, MarvinSketch, and MarvinView as the chemistry tools in many of Pearson MasteringChemistry courses.[18]


Molecule characterization data in the form of a simplified molecular-input line-entry system (SMILES) string can be uploaded into the Marvin software.
