Description

Sodium p-[[3,5-Dibromo-4-[[p-[(2-Cyanoethyl)Ethylamino]Phenyl]Azo]Phenyl]Azo]Benzenesulphonate is a high-purity, synthetic azo dye intermediate characterized by its complex disazo structure and functional sulfonate group. This compound is engineered to deliver exceptional color strength and chemical stability, making it a critical precursor for advanced dye synthesis. It is primarily sought after by manufacturers in the specialty dyes and pigments, textile processing, and advanced materials research sectors for developing high-performance colorants.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the synthesis of high-grade reactive dyes for cotton and other cellulosic fibers.
• Specialty Pigment Manufacturing: Used in the production of complex organic pigments requiring high lightfastness and thermal stability.
• Textile Ink Formulation: Serves as a colorant component in high-resolution digital textile printing inks.
• Functional Dye Synthesis: A precursor for dyes used in non-textile applications, such as lasers, optical data storage, and liquid crystal displays (LCDs).
• Research & Development: Utilized in academic and industrial R&D for exploring novel chromophores and dye-polymer interactions.
• Analytical Chemistry: May be employed as a staining agent or a standard in chromatographic and spectroscopic methods.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC, UV-Vis spectroscopy, and elemental analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 after opening to prevent degradation from atmospheric moisture.
