Description

Trisodium [mu-[7-[[4'-[[6-benzamido-1-hydroxy-3-sulpho-2-naphthyl]azo]-3,3'-dihydroxy[1,1'-biphenyl]-4-yl]azo]-8-hydroxynaphthalene-1,6-disulphonato(7-)]]dicuprate(3-) is a high-purity, complex metal-organic dye compound, specifically a copper phthalocyanine derivative with azo linkages. This product is engineered to deliver exceptional color strength and stability, making it a critical component for demanding industrial applications. It is primarily sought by manufacturers in the textile, specialty ink, and advanced pigment industries who require consistent, high-performance colorants for their formulations.

Application

• Textile Dyeing: Used as a high-grade dye for synthetic fibers, particularly polyesters and nylons, offering excellent wash and light fastness.
• Industrial Pigments: Serves as a key intermediate or final pigment for plastics, coatings, and masterbatches requiring specific hue and thermal stability.
• Specialty Inks: Formulated into high-performance inks for packaging, security printing, and other applications demanding color consistency and durability.
• Functional Dyes: Potential use in advanced applications such as dye-sensitized solar cells (DSSCs) or as a colorant for optical filters due to its complex structure.
• Research & Development: Employed as a reference standard or starting material in chemical research for developing new chromophores and coordination complexes.

Quality Control

Every batch of our trisodium dicuprate complex dye is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for colorants and intermediates. Comprehensive testing includes identity confirmation, purity assay, and critical impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product consistency for your manufacturing processes.

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