03Stereochemistry
The published structure contains 9 defined and 0 unassigned tetrahedral stereocentres. The exact wedge and dash depiction is shown above.
Published same-connectivity configurations
1 recordThese records have the same connectivity, molecular formula and protonation layer, but a different complete InChIKey stereochemical layer. Only separately structure-linked records are shown.

No additional structure-linked configuration with the same connectivity is currently present in the LazyChem dataset.
Scope: The mathematical 2^n value is only an upper bound. Symmetry and other stereogenic elements can change the number of distinct stereoisomers. A hypothetical configuration is not published as a compound record without a verified structure identity.
