Description

Sodium 1-Amino-9,10-Dihydro-4-[[4-[(4-Hydroxyphenyl)Azo]Phenyl]Amino]-9,10-Dioxoanthracene-2-Sulphonate is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its role in synthesizing specialized dyes and pigments with excellent color fastness and light stability properties. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Textile Dyeing: A key intermediate for the synthesis of reactive and acid dyes used on natural and synthetic fibers like cotton, wool, and nylon.
• Ink Manufacturing: Used in the production of high-quality pigments for printing inks, including inks for packaging and security applications.
• Functional Dyes: Serves as a precursor for dyes used in non-textile applications, such as color filters for LCD displays or laser dyes.
• Research & Development: Employed in academic and industrial R&D labs for developing novel chromophores and studying dye chemistry.
• Specialty Coatings: Can be utilized in formulating colored coatings and paints where specific color properties and stability are required.

Quality Control

Our production of Sodium 1-Amino-9,10-Dihydro-4-[[4-[(4-Hydroxyphenyl)Azo]Phenyl]Amino]-9,10-Dioxoanthracene-2-Sulphonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity, consistent color strength, and minimal impurity levels. Certificates of Analysis (COA) detailing purity, identity, and specific tests are available upon request to support your quality assurance and regulatory needs.

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. Keep away from incompatible materials.
