5,6-Dihydroxyindole Use and Manufacturing
Sodium chloride was added to the melanin precursor solution (composed mainly of Dopachrome) obtained in the step 5 to give a final concentration of 2.5percent. The resulting mixture was allowed to stand at room temperature for 45 minutes, whereby conversion of Dopachrome to 5, 6-dihydroxyindole was accelerated compared with the precursor solution free of sodium chloride. Addition of a sodium ascorbate solution instead of sodium chloride caused a marked amount of 5, 6-dihydroxyindole (ratio of 5, 6-dihydroxyindole present in the melanin precursor solution: 90percent).
