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.
Exact-compound status is evaluated only against the published name and CAS number. Confirm the current official instrument before a regulatory decision.
