sdf文件格式怎么打开,SDF文件

Some programs that can import SDF files (e.g. ISIS/Base) require that the first data field after the molecule data (in the example above, Unique_ID) be a unique identifier for each record.

Multiple data items are permitted on multiple lines.[clarification needed] The MDL SDF-format specification requires that a hard-carriage-return character be inserted into any text field whose content exceeds 200 characters. This requirement is frequently violated in practice, as many SMILES and InChI strings exceed that length.
