Assignment statusUnassignedExact published identity
Tetrahedral upper bound≤ 2Before symmetry reduction
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.
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.
Possible structure candidateUnconfirmed identity
A structural result alone does not establish that a nitrosamine forms. A process-specific and analytical assessment is required.
05India status for this compound
