Published same-connectivity configurations

4 records

These 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.

03Structural nitrosamine screen

This is a structure-only screen for the API. It does not predict manufacturing conditions, nitrite exposure, reaction kinetics or analytical results.

N-nitroso groupNot detected

Direct N-nitroso substructure search.

Secondary amine1 site

A detected secondary amine is a structural alert that requires process-specific assessment.

Tertiary N-methyl amineNot detected

N-dealkylation can be relevant to impurity pathway assessment. A methyl group elsewhere in the molecule is not treated as a nitrosamine alert.

Interpretation: Formation potential cannot be concluded from structure alone. Review the synthesis, recovered solvents, amine reagents, nitrite sources, pH, temperature and purge controls.
