Description

9,10-Anthracenedione, 1,4-Bis[(4-Methylphenyl)Amino]-, Sulfonated, Potassium Salts is a specialized, water-soluble derivative of anthraquinone, designed for high-performance applications requiring ionic functionality and chromophoric properties. This compound matters for its unique combination of dye characteristics, metal-complexing ability, and enhanced solubility provided by the sulfonate groups. It is primarily needed by manufacturers in the textile dyeing, functional pigment, and advanced material synthesis industries, where precise color and chemical interaction are critical.

Application

• Textile Dyeing Auxiliary: Acts as an intermediate or functional dye for synthetic fibers like polyester and nylon, providing specific shades and improving fastness properties.
• Functional Pigment & Colorant: Used in the formulation of high-grade inks, coatings, and plastics where light stability and color purity are essential.
• Chemical Synthesis Intermediate: Serves as a key building block for synthesizing more complex anthraquinone derivatives, liquid crystals, or organic electronic materials.
• Analytical Reagent & Indicator: Potential use in laboratory settings as a chromogenic agent or metal ion indicator due to its distinct color change properties.
• Photographic & Imaging Chemicals: Employed in specialized photographic sensitizers or imaging layers.

Quality Control

Our production of 9,10-Anthracenedione, 1,4-Bis[(4-Methylphenyl)Amino]-, Sulfonated, Potassium Salts adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including purity, sulfonation degree, ionic content, and chromatic strength. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance 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, which can affect product performance and handling.
