Description

4-Amino-3,6-Bis[[5-[[4-Chloro-6-[(3-Sulphophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-2-Sulphophenyl]Azo]-5-Hydroxynaphthalene-2,7-Disulphonic Acid is a high-purity, complex reactive dye intermediate of significant commercial importance. Its value lies in its ability to form strong covalent bonds with textile fibers, resulting in exceptional color fastness properties. This compound is primarily required by manufacturers in the textile dyeing and specialty chemical synthesis industries for producing high-performance dyes.

Application

• Primary application in the synthesis of high-grade reactive dyes for cotton, viscose, and other cellulosic fibers.
• Used as a key intermediate for producing dyes with excellent wet fastness, lightfastness, and wash fastness.
• Employed in the manufacture of specialty dyes for niche textile applications requiring brilliant and stable shades.
• Utilized in research and development for creating novel chromophores and advanced colorants.
• Potential use in the coloration of leather and paper, depending on the final derivatization.

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 techniques including HPLC, UV-Vis spectroscopy, and titration methods. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee it meets your specific technical requirements.

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. Keep away from strong acids and incompatible organic solvents.
