Molecular Design Limited (MDL) was founded by Stuart Marson and W. Todd Wipke in 1978, following the latter's experience with E. J. Corey in developing software for planning organic syntheses.[2] The company developed software to store and search chemical structures in large databases under the brand name MACCS (Molecular ACCess System), which was targeted at pharmaceutical and agrochemical companies.[3][4] MDL offered their ISIS (Integrated Scientific Information System) products including ISIS/Draw as components of the MACCS system, specifically to allow chemists to use a graphical interface to register new compounds into corporate databases and to search these databases by structure or part-structure. They also introduced ISIS/Base, a chemical database program suited to the storage of relatively small numbers of structures with associated data for personal use independently of corporate systems. ISIS/Draw structures could be incorporated into other documents, for example using the word processor software which was becoming available in the 1980s, hence providing full electronic publishing for chemists.[5] MDL released many versions of the software and made ISIS/Draw freely available for non-commercial use: version 2.5 was available to run on Windows 98.[6]By 2007, MDL (then owned by Reed Elsevier) merged with Symyx Technologies, which in turn was acquired by Accelrys in 2010 and is now owned by Dassault Systèmes. The software is now branded as BIOVIA Draw.

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]
For scientists engaged in biologics research, new enhancements supporting "chemical sketching is one of the most important capabilities in a chemist's toolkit, particularly given that chemical structures are among the most valuable intellectual property"biomolecules make Symyx Draw 3.1 more efficient than its predecessor ISIS/Draw when it comes to creating, registering, and searching chemically modified peptide or nucleotide sequences. Convenient sequence tools enable scientists to quickly create one- or three-letter amino acids or RNA and DNA sequences. Scientists can easily draw crossing bonds and disulfide bridges and attach side-chain protecting groups using a single tool set. A simple right-mouse click is all it takes to expand an abbreviation to the full structure, change from one-letter to three-letter display, or hide end termini.
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.
This is an introduction to ISIS/Draw, a program from MDL that is free for non-commercial use. You can use it to draw chemical structures, and export them for viewing as 3D models. Instructions for exporting structures for 3D viewing are given on the RasMol page; see "Method 2" there. (Isis/Draw has a menu item called "View molecule in RasMol". It seems to not work properly, and we ignore it here.)
Optional. If you do obtain the program, you may also get the following two optional files:* The AutoNom Standard add-in. This add-in allows you to name structures you draw, and is discussed below under F. Additional useful features in ISIS/Draw. (If the AutoNom installer detects an old version, it will ask you if you want to proceed. You probably want to continue, and install the new version in the correct folder.)* The help file. The basic installation does not include a help file. For basic use the instructions given here should be sufficient.
The AutoNom add-in was first made available to users to Isis/Draw with version 2.4. At that point, its installation was an optional step within the basic package. For version 2.5, the AutoNom add-in is a separate download and installation. If you do not see the Generate Name with AutoNom button, shown above, you need to go back and download/install the add-in. See B. Getting and installing ISIS/Draw.
Naming programs -- especially free ones -- always have limitations. For example, the naming feature of ISIS/Draw does not assign cis/trans (or E/Z) at double bonds when needed. (The naming feature of the alternative drawing program ChemSketch does assigns E/Z.)
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.

ChemDoodle 2D provides an industry leading stoichiometry table. This stoichiometry table is a form where you input theoretical and experimental values from your experiment and you will get accurate calculations for your input and results. ChemDoodle 2D's stoichiometry tables are fully chemically aware and are self-calculating. Input drawn reactions or typed chemical equations are automatically balanced (however you can override these stoichiometric ratios with the Equivalents row) and the limiting component is automatically inferred based on the input values. ChemDoodle 2D enforces the credibility of the calculations for the entire table, and will even warn you if your input is suspicious, for instance, if you have a percent yield greater than 100%.
