isotoniinisiin

Isotoniinisiin is a fictional organic compound used in theoretical chemistry and science fiction to illustrate ideas about isomerism, molecular design, and functional-group interactions. It is not listed in chemical databases and has no experimental record.

In common fictional depictions, isotoniinisiin features a bicyclic core that combines a five-membered nitrogen-containing ring with a fused aromatic ring, creating a moderately polar molecule capable of hydrogen bonding. The imagined structure typically includes one chiral center, leading to enantiomeric forms with distinct properties in narrative contexts.

In synthesis and analysis discussions, isotoniinisiin is described as accessible from simple precursors through cyclization and selective functional-group introduction, with standard characterization by nuclear magnetic resonance, infrared spectroscopy, and mass spectrometry in hypothetical reports.

Applications in fictional or pedagogical contexts include as a neurotransmitter analogue, a catalytic organocatalyst, or a sensor component in model devices. The term is often used to explore how small changes in substituents influence polarity, pKa, and binding interactions in hypothetical systems.

Safety and regulatory notes emphasize that isotoniinisiin is not a real compound; there are no toxicological data, and any depiction is purely illustrative. The concept serves as a placeholder to discuss methodological questions in molecular design and structure–property relationships.
