CAS 482-89-3

Indigo Blue

Description:

Indigo Blue, with the CAS number 482-89-3, is a well-known organic compound primarily recognized for its deep blue color, which has been historically used as a dye in textiles. It is classified as an indole derivative and is characterized by its complex molecular structure, which includes a conjugated system that contributes to its vibrant hue. Indigo Blue is insoluble in water but soluble in organic solvents such as ethanol and acetone, making it suitable for various applications in dyeing processes. The compound exhibits good lightfastness and washfastness, which are essential properties for dyes used in fabrics. Additionally, Indigo Blue has been studied for its potential applications in organic electronics and as a natural dye alternative. Its synthesis can be achieved through several methods, including the traditional fermentation process using plant sources or through chemical synthesis. Despite its widespread use, safety considerations are important, as exposure to high concentrations may pose health risks, necessitating proper handling and safety measures in industrial applications.
