Description

Sodio-5,9-Dianilino-7-Phenyl-4,10-Disulphonatodibenzo[A,J]Phenazinium is a specialized, water-soluble phenazinium dye salt, identified by CAS No. 72379-52-3. This compound is valued for its intense color and functional properties derived from its conjugated aromatic system and sulfonate groups, which enhance solubility and stability in aqueous matrices. It is a critical material for industrial and research applications requiring precise colorants or functional dyes, particularly in the analytical, textile, and specialty chemical sectors.

Application

• As a staining agent or chromogenic substrate in biochemical and histochemical assays.
• Primary use as a specialty dye for textiles, leather, and paper, leveraging its sulfonated structure for good fiber affinity.
• Potential application as a functional dye in the development of sensors and optical materials.
• Use as an intermediate in the synthesis of more complex phenazine derivatives for pharmaceutical or agrochemical research.
• Employed in analytical chemistry as a redox indicator or in colorimetric detection methods.
• Investigated for use in dye-sensitized solar cells (DSSCs) and other photoelectrochemical systems.

Quality Control

Our production of Sodio-5,9-Dianilino-7-Phenyl-4,10-Disulphonatodibenzo[A,J]Phenazinium adheres to stringent internal quality protocols to ensure batch-to-batch consistency and performance. Each lot is characterized and tested for critical parameters including identity, purity, and dye content. A comprehensive Certificate of Analysis (COA) detailing these results is provided with every shipment to support your quality assurance and regulatory 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 tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability.
