The Chemistry Development Kit (CDK) is a library of Java classes for chemo-, bioinformatics, computational chemistry, and chemometrics. It provides important algorithms like substructure search, SMILES, Gasteiger charges, QSAR descriptor calculation, 3D structure generation, 2D layout and rendering, many IO formats, atom typing, and more.

Recent releases


Changes: This release consists of mostly some bugfixes, but also solves a few Java 1.4.2 compile problems and adds more functionality to the SMARTS parser.


Changes: This milestone release fixes a few bugs, contains code clean up for the CML reader, and has a more functional SMARTS query tool.


Changes: This release is the first release candidate for CDK 1.0 and improves performance, has a more consistent API, and fixes many bugs, partly found with the increased JUnit testing.


Changes: This release adds numerous new features, including use of interfaces instead of implementations, updated CMLDOM, curly arrows rendering, much improved PDB reading, Tanimoto distance measure, atomic and bond descriptors, a new interface to R, Gasteiger pi charges, an interface to BioJava, Murcko fragments, a protein pocket finder, support of OWL dictionaries, and much more.


Changes: This release adds atom type matching, improved protein support, copy/paste for the Renderer2D, an iterating CML reader, radical support, and much more. It also fixes many bugs, including some in the isomorphism checker, PDB reading, and CML2 writing.
