Indoxyl
Encyclopedia
In chemistry, indoxyl is a nitrogenous substance with the chemical formula
: C8H7NO. Indoxyl is isomeric with oxindol and is obtained as an oily liquid.
Indoxyl is obtained from indican
, which is a glycoside
. The hydrolysis
of indican
yields β-D-glucose
and indoxyl.
Indigo dye
is a product of the reaction
of indoxyl by a mild oxidizing agent
such as atmospheric oxygen.

Glycoside
In chemistry, a glycoside is a molecule in which a sugar is bound to a non-carbohydrate moiety, usually a small organic molecule. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme...

Hydrolysis
Hydrolysis is a chemical reaction during which molecules of water are split into hydrogen cations and hydroxide anions in the process of a chemical mechanism. It is the type of reaction that is used to break down certain polymers, especially those made by condensation polymerization...

Indigo dye
Indigo dye
Indigo dye is an organic compound with a distinctive blue color . Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. Nearly all indigo dye produced today — several thousand tons each year — is synthetic...

Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity...
