Description

Tetralithium 6-Amino-4-Hydroxy-3-[7-Sulfonato-4-(5-Sulfonato-2-Naphthylazo)-1-Naphthylazo]Naphthalene-2,7-Disulfonate is a high-purity, multi-sulfonated azo dye intermediate of significant industrial importance. This compound is valued for its exceptional water solubility and strong chromophoric properties, making it a critical precursor for advanced colorants. It is primarily required by manufacturers in the textile, ink, and specialty polymer industries for producing vivid, wash-fast dyes and functional pigments.

Application

• Textile Dyeing: As a key intermediate for synthesizing high-performance, water-soluble reactive and direct dyes for cotton, wool, and nylon.
• Inkjet Inks: Used in the production of pigments for high-quality, color-fast inks in commercial and industrial printing.
• Functional Polymers: Acts as a monomer or additive to impart color and ionic functionality to specialty polymers and coatings.
• Liquid Crystal Displays (LCDs): Potential application in the synthesis of dyes for color filters in display technologies.
• Biological Staining: May serve as a precursor for histological stains due to its azo and sulfonate groups.
• Analytical Reagents: Used in the development of colorimetric sensors and indicators for chemical analysis.

Storage

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