MDL introduced specifications for chemical file formats, including the molfile (.mol), and structure/data file (.sdf) which were subsequently placed in the public domain and have become standards for representing structures in 2-D drawings and for transferring such information with associated data, for example identifiers, chemical names and substance properties.[1][4]Many public databases implemented these standards and ChemSpider, for example, allows users to download molfiles for the structures it holds.[7] ISIS/Draw retained its own proprietary file formats with the extension .skc (sketch file) and .rxn (for reactions) and because of its role in preparing database queries it supported a variety of special atom and bond types used for substructure searching, such as wildcard atoms, aromatic bonds, ring bonds, and the atom mapping required for reaction searches.
The current (2020) implementation of the software is called BIOVIA Draw and has several new features such as support for reading and writing International Chemical Identifiers (InChi) and converting IUPAC names into structure drawings. It is freely available for academic and non-commercial use.[11]
Downloading ISIS/Draw for Windows 2.5 from our website was free. The program's installer file is commonly found as IDraw32.exe. The program is sometimes referred to as "ISISDraw for Windows". The program lies within Education Tools, more precisely Science Tools. The actual developer of the free software is Dassault Systems. The following version: 2.5 was the most frequently downloaded one by the program users.
It has the same look-and-feel as its predecessor ISIS/Draw but offers several usability improvements. The all-purpose drawing tool can be used to rapidly sketch structures freehand, including bonds, rings, chains, and atoms, without switching back and forth between tools. Create complex structures and reactions with a single click using a large library of dynamic protecting group templates. Easily rotate part or all of a structure or use the chemical flip tool to flip a structure around its center or around an atom or bond. Rapidly clean up structures or portions of structures by giving them uniform bond lengths and angles and by removing invalid bond marks. 2b1af7f3a8
