A chemical file format is a type of data file which is used specifically for depicting molecular data. One of the most widely used is the chemical table file format, which is similar to Structure Data Format files. They are text files that represent multiple chemical structure records and associated data fields.
Chemical table file (CT file) is a family of text-based chemical file formats that describe molecules and chemical reactions. One format, for example, lists each atom in a molecule, the x-y-z coordinates of that atom, and the bonds among the atoms.

CDXML is the XML analogue of the binary CDX file type used by CambridgeSoft Corporation's ChemDraw chemical structure application. It is considered to be the preferred format for future development. It is considered to be the preferred format for future development.
CDX (ChemDraw Exchange) is a binary file type created by CambridgeSoft Corporation's ChemDraw chemical structure application. CDXML is the XML and preferred version of this format. CDX is the native file format used by ChemDraw to store molecular data, such as atoms, bonds, fragments, arrows and text in a tagged binary format, accurately.
Chemical Markup Language (ChemML or CML) is an approach to managing molecular information using tools such as XML and Java. [1] It was the first domain specific implementation based strictly on XML , first based on a DTD [ 2 ] and later on an XML Schema , [ 3 ] the most robust and widely used system for precise information management in many areas.
Chemical structures and reaction schemes should conform to the following: Images should be drawn with a molecule editor, never freehand; ACS settings should be used for both structures and reaction schemes. These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial.
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.
