Description

Tetrasodium 5-[[4'-[[2,6-Diamino-3-[[8-Hydroxy-3,6-Disulphonato-7-[(4-Sulphonato-1-Naphthyl)Azo]-2-Naphthyl]Azo]-5-Tolyl]Azo][1,1'-Biphenyl]-4-Yl]Azo]Salicylate is a high-purity, water-soluble azo dye intermediate characterized by its complex poly-sulphonated structure. This compound is essential for synthesizing high-value, colorfast dyes and pigments, particularly in applications requiring brilliant shades and excellent stability. It is primarily utilized by manufacturers in the textile, ink, and specialty chemical industries seeking to produce advanced coloring agents.

Application

• Primary Intermediate for Reactive Dyes: A key building block for manufacturing high-performance reactive dyes used in cotton and cellulose fiber dyeing.
• Specialty Pigment Synthesis: Used in the production of complex organic pigments for inks, coatings, and plastics that demand high color strength and weatherfastness.
• Textile Printing Inks: Serves as a crucial component in formulating inks for digital and screen printing on textiles.
• Biological Staining Reagents: Potential use in the synthesis of specialized stains for histological and cytological applications in life sciences.
• Functional Dye Development: A starting material for research and development of dyes for non-textile uses, such as in optical data storage or solar cells.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and meet the exacting standards of our industrial partners. A Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment.

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 sealed to prevent absorption of atmospheric moisture.
