Description

Disodium 5-Amino-9,10-Dihydro-6-Methyl-8-[(4-Methylsulphonatophenyl)Amino]-9,10-Dioxoanthracenesulphonate is a high-purity, water-soluble anthraquinone derivative valued for its functional chromophore. This compound matters for its role as a critical intermediate in the synthesis of specialized dyes and pigments, offering excellent color fastness and stability. It is primarily needed by manufacturers in the textile, ink, and advanced materials sectors for developing high-performance colorants.

Application

• Dye Intermediate: A key precursor for synthesizing reactive, acid, and disperse dyes used in textile coloring.
• Functional Pigment Synthesis: Used in the production of high-stability pigments for inks, coatings, and plastics.
• Research & Development: Serves as a building block in organic synthesis for novel chromophoric materials in academic and industrial R&D.
• Specialty Chemical Manufacturing: Employed in formulating advanced materials where specific light-absorption properties are required.

Quality Control

Our Disodium 5-Amino-9,10-Dihydro-6-Methyl-8-[(4-Methylsulphonatophenyl)Amino]-9,10-Dioxoanthracenesulphonate 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 precise specifications for use in sensitive synthesis processes. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
