Description

4,8-Diamino-1,3,5,7-Tetrahydroxy-9,10-Dioxo-9,10-Dihydroanthracene-2,6-Disulfonic Acid is a highly functionalized anthraquinone derivative, distinguished by its multiple amino, hydroxy, and sulfonic acid groups. This unique molecular architecture makes it a valuable key intermediate and functional chromophore for advanced material synthesis. It is primarily sought after by manufacturers in the specialty dyes and pigments, pharmaceutical intermediates, and analytical reagent sectors, where precise chemical functionality is critical for performance.

Application

• Synthesis of High-Performance Dyes and Pigments: Serves as a crucial precursor for creating complex, water-soluble anthraquinone dyes used in textiles, inks, and specialty coatings.
• Pharmaceutical Intermediate: Utilized in the research and development of active pharmaceutical ingredients (APIs) that require a polyfunctional aromatic core.
• Analytical Chemistry Reagent: Acts as a sensitive chromogenic agent or a complexometric indicator in various spectrophotometric and titrimetric analyses.
• Functional Material Development: Investigated for use in organic electronics, such as in the synthesis of molecules for dye-sensitized solar cells (DSSCs) or conductive polymers.
• Biochemical Research: Potential application as a staining agent or a probe in biochemical assays due to its redox-active and chromophoric properties.
• Catalyst Ligand Synthesis: The multiple coordinating groups make it a candidate for designing novel ligands in metal catalysis.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a cool, dry place with minimal temperature fluctuations, ideally between 15-25°C. For long-term storage, consider desiccants or a controlled atmosphere to prevent moisture uptake, which can affect stability and handling properties.
