Description

Disodium 3-[[2-(Acetylamino)-4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]Phenyl]Azo]Naphthalene-1,5-Disulphonate is a high-purity, reactive dye intermediate of significant commercial importance. Its core value lies in its role as a key building block for synthesizing high-performance dyes and pigments, particularly reactive dyes for textiles. This compound is essential for manufacturers in the textile, ink, and specialty chemical industries seeking to produce vivid, wash-fast colors. Its specific molecular structure allows for strong covalent bonding with cellulose fibers, resulting in superior colorfastness.

Application

• Primary intermediate for the synthesis of reactive dyes used in cotton, linen, and other cellulose fiber dyeing.
• Key precursor in manufacturing azo pigments for inks, plastics, and coatings, providing excellent tinting strength.
• Used in research and development of novel chromophoric systems for advanced optical applications.
• Employed in the production of specialty dyes for leather, paper, and wood staining.
• Acts as a functional intermediate for creating bioconjugates and labeled compounds in biochemical research.
• Serves as a standard or reference material for quality control and analytical method development in dye manufacturing.

Quality Control

Our Disodium 3-[[2-(Acetylamino)-4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]Phenyl]Azo]Naphthalene-1,5-Disulphonate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing assay, impurity profile, and physical characteristics are provided and available upon request, supporting your own 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. Keep away from incompatible materials such as strong oxidizing agents.
