Published same-connectivity configurations

2 records

These records have the same connectivity, molecular formula and protonation layer, but a different complete InChIKey stereochemical layer. Only separately structure-linked records are shown.

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.
