Description

5-[[4-[[4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-7-Sulpho-1-Naphthyl]Azo]-1-Naphthyl]Azo]Naphthalene-1,3,6-Trisulphonic Acid, Ammonium Sodium Salt is a high-purity, water-soluble anionic dye intermediate characterized by its complex polyazo and triazine structure. This compound is engineered for exceptional color strength and binding affinity, making it a critical precursor for synthesizing high-performance dyes and pigments. It is primarily required by manufacturers in the textile, leather, and specialty ink industries seeking to produce vivid, wash-fast, and light-stable colorants.

Application

• Primary Intermediate for Reactive Dyes: A key building block in the synthesis of high-grade reactive dyes for cotton, wool, and nylon, offering excellent fiber fixation.
• Leather Dyeing: Used in the production of dyes for leather finishing, providing deep, uniform shades with good rub fastness.
• Inkjet Ink Formulation: Serves as a precursor for pigments used in high-quality digital textile printing and specialty inks.
• Paper Coloring: Employed in the manufacture of dyes for specialty paper products requiring bright and stable colors.
• Research & Development: Utilized in chemical R&D for developing new chromophores and studying azo dye chemistry and applications.

Quality Control

Our production of this dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing specific test results are provided with every shipment to support your quality assurance and regulatory compliance 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 sealed to prevent absorption of atmospheric moisture.
