Description

Dibarium 6,6'-[(3,3'-Dimethoxy[1,1'-Biphenyl]-4,4'-Diyl)Bis(Azo)]Bis[4-Amino-5-Hydroxynaphthalene-1,3-Disulphonate] is a high-purity, barium-based azo dye intermediate of significant industrial importance. Its complex molecular structure, featuring a biphenyl azo core with amino and hydroxynaphthalene disulphonate groups, makes it a critical precursor for synthesizing specialized pigments and dyes. This compound is essential for manufacturers requiring precise colorants with specific metal-ion characteristics. It is primarily utilized in advanced applications within the pigment, specialty chemical, and research sectors.

Application

This specialized barium salt serves as a key building block in several high-value industrial processes. Its primary and related applications include:

• Precursor for High-Performance Pigments: Synthesis of complex azo pigments, particularly those requiring barium for improved lightfastness, heat stability, and specific hue development.
• Specialty Dye Manufacturing: Production of dyes for niche applications where the barium ion imparts unique solubility or substrate affinity properties.
• Research & Development: Used as a standard or intermediate in chemical research for developing new colorants, functional materials, or coordination complexes.
• Analytical Reagent: Potential use as a specialized reagent in analytical chemistry for colorimetric detection or as a metal-ion source in controlled reactions.
• Functional Material Synthesis: Exploration in creating metal-organic frameworks (MOFs) or other advanced materials due to its polyfunctional ligand structure.

Quality Control

Our production of Dibarium 6,6'-[(3,3'-Dimethoxy[1,1'-Biphenyl]-4,4'-Diyl)Bis(Azo)]Bis[4-Amino-5-Hydroxynaphthalene-1,3-Disulphonate] adheres to a stringent quality management system to ensure batch-to-batch consistency and reliability for industrial synthesis. All products undergo rigorous quality testing, including spectroscopic identification and purity assays, to ensure compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, heavy metal content, and other critical parameters is provided with each shipment to support your quality assurance protocols.

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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance and handling.
