Description

4-Amino-5-hydroxy-3-[[4-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]azo]-2,7-naphthalenedisulfonic acid, sodium salt coupled with diazotized 2-amino-4-[[4-chloro-6-[[2-[2-[(2-chloroethyl) sulfonyl]ethoxy]ethyl]amino]-1,3,5-triazin-2-yl]amino]benzenesulfonic acid is a high-performance, reactive bifunctional dye intermediate designed for creating durable colorants. This compound is engineered to deliver superior wash-fastness and light-fastness properties in demanding applications. It is primarily required by manufacturers in the textile, leather, and specialty ink industries seeking to produce high-quality, colorfast products.

Application

Reactive Dye Synthesis: A key intermediate for manufacturing high-grade reactive dyes for cotton, viscose, and other cellulosic fibers.
Textile Printing and Dyeing: Used in formulations for printing inks and dye baths requiring excellent covalent bonding to fabric.
Leather Coloring: Employed in the production of dyes for leather finishing, offering deep, permanent coloration.
Paper Dyeing: Suitable for specialty paper grades where high color strength and stability are needed.
Inkjet Inks: A component in the synthesis of pigments for industrial and textile inkjet printing.
Research & Development: Serves as a precise chemical building block in R&D for novel chromophores and functional dyes.

Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through advanced analytical techniques including HPLC and spectrophotometry. Certificates of Analysis (COA) documenting purity, strength, and impurity profiles are available upon request to support your 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 use to prevent degradation from atmospheric moisture.
