Description

1,5-Naphthalenedisulfonic acid, 3-[[2-(acetylamino)-4-aminophenyl]azo]-, disodium salt, reaction products with 2-[[4-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]phenyl]sulfonyl] ethyl hydrogen sulfate, hydrolyzed is a specialized reactive dye intermediate, specifically a hydrolyzed form of a bifunctional reactive dye system. This compound is engineered to provide enhanced covalent bonding to cellulosic fibers, offering superior wash and light fastness properties. It is a critical raw material for manufacturers of high-performance textile dyes, particularly for applications requiring deep, vibrant colors with excellent durability. The product, identified by CAS 319926-36-8, is supplied to meet the stringent demands of industrial-scale dye synthesis.

Application

Primary Intermediate for Reactive Dyes: Key starting material for synthesizing high-quality reactive dyes used in textile coloring.
Cellulosic Fiber Dyeing: Specifically designed for dyeing cotton, viscose, linen, and other cellulosic materials.
High-Fastness Textile Production: Enables the production of dyes with exceptional fastness to washing, light, and perspiration.
Industrial Textile Manufacturing: Used in continuous and exhaust dyeing processes for apparel, home textiles, and technical fabrics.
Specialty Colorant Synthesis: Serves as a precursor for creating specific, vibrant shades (e.g., deep blues, blacks, and navies) in the color palette.
Research & Development: Utilized in R&D labs for developing new dye formulations and improving existing dyeing technologies.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through analytical methods including HPLC for purity and assay, and spectroscopic techniques for structural confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with each shipment. We support our global clients with documentation compliant with industry and regional standards.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials.
