http://x3dna.bio.columbia.edu/data/ctfile.pdf 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.
