Description

6-[[6-[[(2,3-Dichloroquinoxalin-6-Yl)Carbonyl]Amino]-1-Hydroxy-3,5-Disulpho-2-Naphthyl]Azo]Naphthalene-1,3,5-Trisulphonic Acid, Potassium Sodium Salt is a high-purity, water-soluble anionic dye intermediate with a complex polycyclic structure. This compound matters for its exceptional chromophoric properties and ability to form stable, intense color complexes with various metal ions. It is primarily needed by manufacturers in the textile, specialty ink, and analytical reagent industries seeking to produce high-performance dyes and colorimetric detection agents.

Application

• Textile Dye Intermediate: A key precursor for synthesizing high-grade, wash-fast reactive and direct dyes for cotton, wool, and nylon.
• Specialty Ink Formulation: Used in the production of high-visibility security inks and specialty printing inks requiring specific lightfastness and solubility.
• Analytical Chemistry Reagent: Serves as a sensitive chromogenic agent in colorimetric assays and metal ion detection kits.
• Biological Staining: Potential use in the development of histological stains for microscopy due to its strong affinity for certain tissue structures.
• Laser Dye & Optical Applications: Can be utilized in research for tuning laser dyes and other photonic materials.
• Paper Coloring: Suitable for high-quality paper products where specific color tones and stability are required.
