Verwenden
Lumiflavin is a toxic photolysis product of vitamin B2 (R415000).
läuterung methode
Lumiflavin forms orange crystals upon recrystallisation from 12% aqueous AcOH, or from formic acid. It sublimes at high vacuum. It is freely soluble in CHCl3, but not very soluble in H2O and most organic solvents. In H2O and CHCl3 solution it has a green fluorescence. UV has max at 269, 355 and 445nm ( 38,800, 11,700 and 11,800, respectively) in 0.1N NaOH and 264, 373 and 440nm ( 34,700, 11,400 and 10,400, respectively) in 0.1N HCl, while the UV in CHCl3 has max at 270, 312, 341, 360, 420, 445 and 470nm.
