Description

Sodium 4-[(4,8-Diamino-3,7-Dibromo-9,10-Dihydro-9,10-Dioxo-1-Anthryl)Amino]Toluene-3-Sulphonate is a high-purity, water-soluble anthraquinone derivative valued for its chromophoric and functional properties. This compound is engineered to deliver consistent performance as a key intermediate in the synthesis of specialized dyes and pigments. It is primarily sought by manufacturers in the textile, ink, and advanced materials sectors who require reliable, high-quality intermediates for colorant production.

Application

• Primary Intermediate for Anthraquinone Dyes: Serves as a critical building block in the synthesis of high-value, colorfast blue and green dyes for textile and industrial applications.
• Specialty Ink Formulations: Used in the production of pigments for high-performance inks, including those for security printing and digital textiles.
• Functional Dye Synthesis: A precursor for dyes used in non-textile applications such as liquid crystal displays (LCDs) and optical data storage.
• Research & Development: Employed in academic and industrial R&D labs for developing novel chromophores and studying structure-property relationships in dye chemistry.
• Analytical Chemistry: Can be utilized as a staining agent or a standard in chromatographic and spectroscopic analysis due to its distinct chemical signature.

Quality Control

Every batch of our Sodium 4-[(4,8-Diamino-3,7-Dibromo-9,10-Dihydro-9,10-Dioxo-1-Anthryl)Amino]Toluene-3-Sulphonate is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards through rigorous in-process and final release testing, including identity confirmation, purity assay, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each 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 stability and performance.
