Description

1,5-Naphthalenedisulfonic Acid, 3-[[4-[[4-Chloro-6-[(2-Hydroxyethyl) Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Methoxy -2-Methylphenyl]Azo]-, Disodium Salt is a high-purity, reactive dye intermediate belonging to the azo dye chemical class. This compound is valued for its ability to impart vibrant and stable colors, particularly in demanding applications where lightfastness and washfastness are critical. It is primarily needed by manufacturers in the textile, ink, and specialty polymer industries for producing high-performance dyes and pigments.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in cotton, wool, and nylon fiber dyeing and printing.
• Textile Colorants: Imparts excellent color yield, brightness, and superior fastness properties (light, wash, and perspiration) to finished fabrics.
• Inkjet Ink Formulations: Used in the production of pigments for industrial and commercial inkjet inks requiring high color purity and stability.
• Specialty Polymer Coloring: Suitable for coloring engineering plastics and synthetic fibers where high-temperature processing stability is required.
• Research & Development: Serves as a crucial chemical entity in R&D labs for developing new chromophores and functional dyes.
• Leather Dyeing: Employed in the formulation of dyes for leather finishing, offering deep penetration and uniform coloration.

Quality Control

Our production of this dye intermediate adheres to strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

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 opening to prevent degradation from atmospheric moisture.
