What Are CTfile and CTAB

This section provides a quick introduction of the SDF (Structure Data File) format. An example of SDF file is also provided.

What CTfile (Chemical Table File)? CTfile referes to six file formats that are used to store chemical information in a table style. All CTfile formats shares a common structure called CTAB (Connection Table), which describes the structural relationships and properties of a collection of atoms.

Below are short descriptions of CTfile formats:

CTfile formats have 2 versions: V3000 and V2000.
