Ketcher

Ketcher is an open-source web-based chemical structure editor incorporating high performance, good portability, light weight, and ability to easily integrate into a custom web-application. Ketcher is designed for chemists, laboratory scientists and technicians who draw structures and reactions. - ⚡️ Fast 2D structure representation that satisfies common chemical drawing standards - 3D structure visualization - Template library (including custom and user's templates) - 🔩 Add atom and bond basic properties and query features, add aliases and Generic groups - Stereochemistry support during editing, loading, and saving chemical structures - Storing history of actions, with the ability to rollback to previous state - Ability to load and save structures and reactions in MDL Molfile or RXN file format, InChI String, ChemAxon Extended SMILES, ChemAxon Extended CML file formats - Zoom in/out, hotkeys, cut/copy/paste - OCR - ability to recognize structures at pictures (image files) and reproduce them - Copy and paste between different chemical editors - 🛠️ Settings support (Rendering, Displaying, Debugging) - Use of SVG to achieve best quality in-browser chemical structure rendering - Atom Tool, Bond Tool, and Template Tool to draw and edit structures - Aromatize/De-aromatize Tool - Calculate CIP Descriptors Tool - Structure Check Tool - MW and Structure Parameters Calculate Tool - Select, modify, and erase connected and unconnected atoms and bonds using Selection Tool, or using Shift key - Advanced Structure Clean up Tool (+ stereochemistry checking and structure layout) - Simple Structure Clean up Tool (checks bonds length, angles and spatial arrangement of atoms) - Easy to use R-Group and S-Group tools (Generic, Multiple group, SRU polymer, peratom, Data S-Group) - Reaction Tool (reaction generating, manual and automatic atom-to-atom mapping) - Flip/Rotate Tool Ketcher is the open-source project epam/ketcher (https://github.com/epam/ketcher) by epam, released under Apache-2.0. Ion packages it unmodified from commit 44b6cf9ebb06, adding only a manifest, an icon and a storage compatibility script.
