kojicsyre

Kojicsyre is a fictional chemical compound described in speculative chemistry and science fiction contexts. In these narratives it is portrayed as a stable organosulfur–oxide derivative with a conjugated framework that imparts redox activity. The hypothetical formula is given as C13H8O6S2, and the substance is described as forming dark monoclinic crystals with a melting point around 260–270°C. It is typically said to be sparingly soluble in water and soluble in common organic solvents.

In fictional syntheses, kojicsyre is produced by the oxidation of a kojic acid derivative using sulfur chlorides or sulfuryl chloride under elevated temperature, often with a tertiary amine catalyst. The compound is described as redox-active and capable of mediating electron transfer in imagined catalytic cycles, sometimes referred to as a mild oxidant or electron mediator. Its stability under atmospheric conditions is noted within the stories, enabling its use in various laboratory and materials contexts.

Applications within these works include catalytic cross-coupling reactions and as a pigment-forming agent in speculative materials or coatings. The name kojicsyre is commonly presented as a portmanteau of kojic acid and the suffix -syre, signaling a sulfur-containing derivative; some depictions credit the term to researchers in a fictional setting or publication series.

Note: Kojicsyre is not a real-world substance and has no peer-reviewed or practical validation outside fictional contexts. It should be treated as a construct of speculative chemistry rather than established science. See also kojic acid, sulfur-containing compounds, fictional chemistry.
