MCDL notation, including supplementary data, of Aspirin[1]
The Modular Chemical Descriptor Language(MCDL) is a method for representing of molecular structures and pertinentmolecular information using linear descriptors. MCDL files are designed for cross-platform transfer and manipulation of compound-specific chemical data. They consist of sets of unique information (fragments, connections) and nonunique information (coordinates, ID numbers, spectra, physical-chemical properties). The nonunique portion of the descriptor can be customized, thus providing end-user flexibility.[1] Unique representation of atom and double bond stereochemistry is contrived as separate modules.[2]
Software implementation
Modular Chemical Descriptor Language is currently implemented in several software packages. A JAVA-based MCDL editor with intelligent generation of 2D coordinates is available as open source software under GPL.[3] MCDL translator is also included in Open Babel starting from version 2.3.1.[4][5]
