6 defined, 0 unassigned centres

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.
04Possible N-nitroso structures
A record-level structural review indicates a possible N-nitroso candidate. This is not a confirmed impurity, formation prediction or analytical finding.
A structural result alone does not establish that a nitrosamine forms. A process-specific and analytical assessment is required.
05India status for this compound
