Assignment statusFully assignedExact published identity
Tetrahedral upper bound≤ 8Before symmetry reduction
Published same-connectivity configurations
3 recordsThese 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.
