Published same-connectivity configurations

2 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.

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
Possible N-nitroso structural candidate related to ((R)-5-(2-((5,6-diethyl-2,3-dihydro-1H-inden-2-yl)amino)-1-ethoxyethyl)-8- hydroxyquinolin-2(1H)-one)
No CAS number, formation claim or analytical confirmation is assigned.

A structural result alone does not establish that a nitrosamine forms. A process-specific and analytical assessment is required.
