Tautomerize

This action creates a canonical/standard tautomer form of the molecule.

The created tautomer:

• represents a group of tautomers which can transform into each other;

• is supposed to be a stable tautomer (normal canonical tautomer).

• from version 23.3.0 tautomerize action can also create the canonical tautomer: tautomerize:canonical

• the default is the normal canonical tautomer: tautomerize or tautomerize:normalCanonical

  ​

Example :

Action	Input	Output
Tautomerize (tautomerize)
Tautomerize:normalCanonical (tautomerize)
Tautomerize:canonical

Note :

• The created tautomer is always returned in dearomatized form.

• Action "tautomerize" ungroups all S-groups. After performing "tautomerize", the molecules will not contain any S-groups.
