Lumichrome (7,8-Dimethylalloxazine) is a natural metabolite of riboflavin. It is a flourescent photoproduct of riboflavin degradation. It is known to be an effective photosensitiser and a fluorescent dye. Lumichrome is suitable as a fluorescence probe, metal ion sensor, and may be used for the inactivation of biological contaminants. Its applications are also seen in memory and semiconductor devices.
