カール・ヴィルヘルム・シェーレ
Alloxan was used in the production of the purple dye murexide, discovered by Carl Wilhelm Scheele in 1776. Murexide is the product of the complex "in-situ" multistep reaction of alloxantin and gaseous ammonia. Murexide results from the condensation of the unisolated intermediate uramil with alloxan, liberated during the course of the reaction.
