03Stereochemistry
The published structure contains 0 defined and 1 unassigned tetrahedral stereocentre. The exact wedge-and-dash depiction is shown above.
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.
A structural result alone does not establish that a nitrosamine forms. A process-specific and analytical assessment is required.
05India status for this compound
These results apply only to this exact compound name and CAS number. Confirm the current official instruments before making a regulatory decision.
