5,6-Dihydroxyindole
What is 5,6-Dihydroxyindole?
5,6-Dihydroxyindole is an important intermediate in melanin
production. Melanin is formed from tyrosine in the body through a
series of enzymatic oxidation reactions. One of the most important
intermediates in this process is 5,6-dihydroxyindole. This
substance is naturally occurring in the body, making it non-toxic,
with few side effects, and avoiding the carcinogenic, teratogenic,
and allergenic effects of hair dyes made from p-phenylenediamine
and its derivatives. 5,6-Dihydroxyindole has a small molecular
weight and, as a permanent hair dye, operates on the same mechanism
as other dyes: it penetrates the hair shaft and undergoes oxidative
polymerization to form a colored macromolecule that is then fixed
in place. Currently, it is being used in some personal care
products to replace aniline and phenolic compounds.

5,6-Dihydroxyindole is also an intermediate in the formation of some amino acids,
alkaloids, and tryptamines, and it has a good effect on dyeing
keratin fibers.

Package & Storage
Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during
transportation, we will carry out more delicate packaging. For
example, retinal needs to be stored at -20 °C, so we choose cold
chain transportation during transportation; deoxyarbutin will
change color during transportation, so we will Vacuum packing of
deoxyarbutin
