Description

Tetrasodium 3-[[8-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-1-Hydroxy-3,6-Disulphonato-2-Naphthyl]Azo]-4-Hydroxynaphthalene-1,5-Disulphonate is a high-performance, water-soluble reactive dye intermediate and specialty chemical. This compound matters for its ability to form strong covalent bonds with substrates like cellulose, providing excellent wash and light fastness properties. It is primarily needed by manufacturers in the textile, paper, and leather industries for producing vibrant and durable colorants.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in cotton, viscose, and other cellulosic fiber dyeing and printing.
• Textile Industry: Imparts brilliant shades with superior fastness properties, including resistance to washing, light, and perspiration.
• Paper Coloring: Used in the production of specialty colored papers where high color strength and stability are required.
• Leather Finishing: Employed in dyeing leather goods to achieve deep, uniform, and long-lasting colors.
• Ink Formulation: A component in the manufacture of certain industrial inks requiring specific chromatic properties and stability.
• Research & Development: Serves as a precise chemical entity for R&D in novel chromophore systems and advanced material science.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
