JChemPaint (or JCP for short) is the editor and viewer for 2D chemical structures developed using the Chemistry Development Kit (CDK).
It is implemented in several forms: a Java application and two varieties of Java applet.
This is free and open source software.
Key Features
- Drawing and deletion of single, double, triple and stereo bonds.
- Ring templates (3-8 atoms) with one-click attachment.
- An extensive template library.
- Colouring of atom types, and other rendering settings.
- Editing of atomic charges, isotopes and hydrogen count.
- Loading and saving of structures in Chemical Markup Language (CML) and as MDL MOL files and SDF files (loading only).
- Automated Structure Layout, also known as Structure Diagram Generation.
- Loading structures from the Internet using CAS or NSC number.
- Normalization of structures, currently limited to aromaticity detection.Saving bitmap pictures of the structures.
- Saving structures as graphics (PNG, BMP, Scalable Vector Graphics (SVG)).
- Postscript printing.
