Lisaksin

Lisaksin is a fictional chemical compound commonly used in science education and speculative fiction to illustrate reaction pathways and material behavior. It does not correspond to any known substance in real-world chemistry. The term lisaksin appears in several textbooks and narrative works to show how a single compound can participate in multiple reaction types, such as nucleophilic addition, electrophilic substitution, and catalytic cycles, depending on the chosen reagents and conditions.

In educational contexts, lisaksin is described as a small organic molecule with a flexible backbone and a functional group that can be modified to yield derivatives with distinct properties. The fictional properties of lisaksin are deliberately variable across sources, allowing instructors to tailor problem sets and readers to different scenarios. In literature, lisaksin is sometimes depicted as a reactive intermediate or a reagent with tunable reactivity, enabling plot devices around chemical synthesis or material fabrication. Because lisaksin is imaginary, real-world safety data, synthesis routes, and regulatory status do not apply. The concept is used to discuss general chemistry topics without implying the existence of a real compound. See also fictional chemical compounds, science education, chemistry in fiction.
