Description

7-Benzothiazolesulfonic acid, 2-[4-[[4-[[3-[[5-(aminocarbonyl)-1-ethyl-1,6-dihydro-2-hydroxy-4-methyl-6-oxo-3-pyridinyl]azo]-4-sulfophenyl] amino]-6-chloro-1,3,5-triazin-2-yl]amino] phenyl]-6-methyl-, disodium salt is a high-purity, complex azo dye intermediate featuring a reactive triazine group. This compound is critically important for synthesizing high-performance, wash-fast reactive dyes and pigments used in demanding textile applications. It is primarily required by manufacturers in the textile dye and specialty chemical industries seeking to produce vibrant, durable colors for cotton and other cellulose fibers.

Application

Primary intermediate for reactive dyes used in textile dyeing and printing processes.
Key component in the synthesis of high-washfastness dyes for cellulosic fibers like cotton, viscose, and linen.
Used in the production of specialized pigments for inks and coatings requiring specific color properties.
Employed in research and development for novel colorants and functional dyes with enhanced properties.
Potential use in the synthesis of dyes for leather and paper applications.

Quality Control

Our production of this advanced dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and reliability for your synthesis processes. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key specifications such as assay, impurity profile, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
