Understanding Acid Red 92

Acid Red 92, also known by its chemical name 3-Hydroxy-4-[(2-methoxy-5-methyl-4-sulfophenyl)azo]-2,7-naphthalenedisulfonic acid, trisodium salt, is an anionic dye belonging to the azo dye family. It is water-soluble and has excellent affinity for protein fibers such as wool, silk, and nylon. The dye is commonly used in the textile, leather, and paper industries, as well as in the production of food and cosmetics.

The Color Range of Acid Red 92

The color range of Acid Red 92 is primarily characterized by its bright and intense red hues. It can produce a spectrum of red shades, from a vivid scarlet to a deep, rich crimson.
