Description

Trisodium Hydrogen 4-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(1-Sulphonato-2-Naphthyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]Benzoate CAS NO 70776-19-1 is a high-purity, water-soluble reactive dye intermediate characterized by its complex polyazo and triazine structure. This compound is essential for synthesizing high-performance, colorfast dyes and pigments, particularly for demanding applications where wash-fastness and light stability are critical. It is primarily utilized by manufacturers in the textile, ink, and specialty coatings industries seeking to produce vibrant and durable colors.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing high-quality reactive dyes used in cotton, wool, and nylon dyeing and printing.
• Textile Industry: Enables the production of dyes with excellent fixation rates, brilliant shades (especially reds and blues), and superior fastness properties to washing, light, and perspiration.
• Inkjet Inks: Used in the synthesis of pigments for high-performance digital textile printing inks, ensuring color vibrancy and durability.
• Leather Coloring: Serves as an intermediate for dyes applied in the leather tanning and finishing industry.
• Paper Coloring: Employed in the production of dyes for specialty paper and packaging that requires high color strength.
• Research & Development: Used in chemical R&D laboratories for developing new chromophores and studying dye-polymer interactions.

Quality Control

Our Trisodium Hydrogen 4-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(1-Sulphonato-2-Naphthyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]Benzoate is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, chemical identity, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and solubility are available upon request 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 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.
