Description

Disodium 7-[(4-Chloro-6-Methoxy-1,3,5-Triazin-2-Yl)Methylamino]-4-Hydroxy-3-[(2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate is a high-purity, reactive dye intermediate essential for modern colorant synthesis. This compound is valued for its ability to form stable covalent bonds with substrates, resulting in excellent wash and light fastness in the final colored products. It is a critical raw material for manufacturers in the textile, paper, and specialty ink industries seeking to produce vibrant, durable colors.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-performance reactive dyes used in cotton, viscose, and other cellulosic fiber dyeing and printing.
• Textile Industry: Enables the production of dyes with superior color yield and fixation rates, crucial for achieving consistent and brilliant shades on fabrics.
• Paper Coloring: Used in the manufacture of dyes for high-quality, color-fast paper products.
• Specialty Inks: Serves as a precursor for pigments and dyes in inks requiring enhanced stability and brightness.
• Research & Development: Employed in chemical R&D for developing novel chromophores and studying azo-triazine chemistry.
• Leather Processing: Potential application in the development of dyes for leather with improved penetration and fastness properties.

Quality Control

Every batch of our reactive dye intermediate is produced and tested under a strict quality management system. We ensure compliance with industry standards through rigorous in-process and final product controls. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your manufacturing processes.

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.
