Description

1-Amino-9,10-Dihydro-9,10-Dioxo-4-[[3-[[[2-(Sulfooxy)Ethyl]Sulfonyl]Methyl]Phenyl]Amino]-2-Anthracenesulfonic Acid Disodium Salt is a high-purity, water-soluble anthraquinone derivative engineered for demanding industrial applications. This compound is valued for its functionalized structure, which provides excellent reactivity and binding properties in specialized chemical syntheses. It is a critical intermediate for manufacturers in the dyestuff, specialty chemical, and advanced materials sectors seeking consistent quality and reliable supply.

Application

• Key Intermediate for Reactive Dyes: Primarily used in the synthesis of high-performance reactive dyes for textiles, particularly for cellulose fibers like cotton, providing excellent wash and light fastness.
• Specialty Pigment Manufacturing: Serves as a precursor in the production of high-value, color-stable organic pigments for inks, coatings, and plastics.
• Functional Dye Synthesis: Used in creating functional dyes for non-textile applications, including sensitizers for solar cells and colorants for electronic displays.
• Biochemical Research: May be utilized as a chromophore or a tagged reagent in biochemical assays and diagnostic research due to its strong visible light absorption.
• Photographic Chemicals: Can function as a specialized component in the formulation of advanced photographic and imaging chemicals.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability.
