Description

7-[[2-[(aminocarbonyl)amino]-4-[[4-[[5-[(4-amino-9,10-dihydro-9,10-dioxo-3-sulpho-1-anthryl)amino]-2-sulphophenyl]amino]-6-chloro-1,3,5-triazin-2-yl]amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid is a high-performance, polyfunctional reactive dye intermediate of significant industrial importance. Its complex molecular structure, featuring multiple sulphonic acid groups and a reactive triazine chloride, provides excellent water solubility and strong covalent bonding capabilities to substrates. This compound is essential for manufacturers requiring vivid, wash-fast colors in demanding textile and specialty material applications. Its properties make it a critical component for producing advanced dye formulations.

Application

Primary application in the synthesis of high-grade reactive dyes for cotton, viscose, and other cellulosic fibers.
Used in the production of dyes for textile printing and dyeing, offering excellent color yield and fastness properties.
Serves as a key intermediate for dyes used in leather coloring processes.
Potential use in the manufacture of inkjet inks for specialized digital textile printing.
Applicable in the research and development of functional dyes for non-textile uses, such as in analytical chemistry or sensors.
Used for coloring paper and other related substrates where water-soluble, reactive colorants are required.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive analytical testing, including HPLC for purity and identity confirmation. A Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with each shipment to guarantee it meets your formulation 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 when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and organic solvents.
