Description

Tetrasodium [Mu-[[3,3'-[Azoxybis[(2-Hydroxy-p-Phenylene)Azo]]Bis[4-Hydroxy-6-(3-Sulphoanilino)Naphthalene-2-Sulphonato]](8-)]]Dicuprate(4-) is a complex, high-purity copper-based azo dye intermediate. This compound is valued for its role as a critical precursor in the synthesis of specialized, high-performance dyes and pigments. It is primarily required by manufacturers in the colorant industry, particularly for producing dyes with enhanced lightfastness and color strength for textiles, inks, and advanced materials.

Application

Primary Intermediate for Azo Dyes: Serves as a key building block in the synthesis of complex, high-value azo dyes and pigments.
Textile Dye Manufacturing: Used to produce dyes for coloring natural and synthetic fibers, offering good wash and light fastness.
Specialty Ink Production: A precursor for pigments used in high-performance printing inks, including packaging and security inks.
Functional Colorants: Potential use in the development of dyes for non-textile applications, such as in coatings and plastics.
Research & Development: Employed in chemical R&D for creating novel chromophores with specific optical properties.

Quality Control

Our production of this specialty intermediate adheres to strict quality control protocols to ensure batch-to-batch consistency and purity. Quality is verified through analytical techniques including HPLC and spectrophotometry. A Certificate of Analysis (COA) detailing purity, identity, and relevant specifications is provided with every shipment to support your quality assurance processes.

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 after opening to prevent degradation from atmospheric moisture.
