"WebThe "chiral flag" is a feature that was used in MDL v2000 mol files, but was superseded by Enhanced Stereo Groups, which are much more flexible, in the v3000 format. It would be useful to have some infrastructure that allows us to "translate" the stereochemistry read from a v2000 mol block into Enhanced Stereo Groups. If my understanding of the ...

WebNo chiral flag set means that only the relation is known between the tetrahedral stereo centers. The stereocenter could be either of the two stereomers (as drawn and the mirror image) or a mixture of the two. In JChem the chiral flag representation of MDL is not considered by default and all molecules are treated as chiral: Table 8. WebJan 8, 2024 · The issue with the chiral flag not set in the SD-file is a V2000 problem, not V3000. The fifth entry in the counts line of a V2000 molfile encodes, whether the structure is a racemate or not (0 or 1). For racemates DataWarrior must normalise the configuration, because DataWarrior stores canonical structure representations.
