482-89-3 structure, C16H10N2O2

Indigo

CAS No.

482-89-3

Formula:

C16H10N2O2

Basic Info

Indigo dye is an organic compound with a distinctive blue color (see indigo). Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. A large percentage of indigo dye produced today – several thousand tons each year – is synthetic. It is the blue often associated with blue jeans.
