Description

Disodium 4,4'-[(9,10-Dihydro-5,8-Dihydroxy-9,10-Dioxo-1,4-Anthrylene)Diimino]Bis[3,5-Diethyltoluene-2-Sulphonate] is a high-purity, water-soluble anthraquinone derivative dye intermediate. This compound is valued for its excellent chromophoric properties and stability, making it a critical precursor for synthesizing specialized dyes and pigments. It is primarily needed by manufacturers in the textile, ink, and specialty chemical industries for producing high-performance colorants.

Application

• Textile Dye Intermediate: A key precursor for synthesizing reactive and acid dyes used in coloring natural and synthetic fibers.
• Inkjet Ink Formulation: Used in the production of high-quality, light-fast colorants for industrial and graphic arts inks.
• Functional Dye Synthesis: Serves as a building block for dyes used in optical data storage, liquid crystal displays (LCDs), and other advanced optical applications.
• Biological Staining Agent: Potential use as an intermediate for developing histological stains and diagnostic dyes in life sciences.
• Polymer Colorant: Imparts color to plastics and polymers where high thermal stability and compatibility are required.
• Analytical Chemistry Reagent: Can be utilized as a chromogenic agent or indicator in specific analytical methods.

Quality Control

Our Disodium 4,4'-[(9,10-Dihydro-5,8-Dihydroxy-9,10-Dioxo-1,4-Anthrylene)Diimino]Bis[3,5-Diethyltoluene-2-Sulphonate] is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements of industrial dye synthesis. Certificates of Analysis (COA) detailing purity, impurity profile, and physical characteristics are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption and degradation.
