CAS 522-75-8

Thioindigo

Description:

Thioindigo, with the CAS number 522-75-8, is an organic compound belonging to the class of indigo derivatives. It is characterized by its deep blue to violet color, which is attributed to its conjugated double bond system that allows for extensive delocalization of electrons. Thioindigo features a sulfur atom replacing one of the nitrogen atoms found in traditional indigo, contributing to its unique properties. This compound is known for its stability and is often used as a dye in textiles and other applications due to its vibrant color and resistance to fading. Thioindigo exhibits solubility in organic solvents, while being relatively insoluble in water, which is typical for many organic dyes. Its chemical structure allows for various functionalizations, making it a versatile compound in synthetic organic chemistry. Additionally, thioindigo has been studied for its potential applications in organic electronics and photonic devices, owing to its electronic properties and ability to form charge-transfer complexes.
