Description

2,7-Naphthalenedisulfonic Acid, 5-4-Fluoro-6-(4-Morpholinyl)-1,3,5-Triazin-2-Ylamino-4-Hydroxy-3-(1-Sulfo-2-Naphthalenyl)Azo-, Potassium Sodium Salt is a high-purity, complex azo dye intermediate designed for advanced colorant synthesis. This compound is critical for producing high-performance dyes with excellent light and wash fastness properties. It is primarily required by manufacturers in the textile, ink, and specialty polymer industries seeking to develop vibrant and durable colorants.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-grade reactive dyes used in cotton and cellulose fiber dyeing.
• Specialty Ink Formulations: Used in the production of inks for digital textile printing and high-resolution inkjet applications.
• Functional Dye Synthesis: Serves as a precursor for dyes used in optical data storage, liquid crystal displays (LCDs), and other electronic applications.
• Textile Colorants: Enables the creation of deep, vivid shades with superior fastness to light, washing, and perspiration.
• Research & Development: A valuable compound for R&D chemists developing novel chromophores and dye-sensitized materials.
• Polymer Staining: Can be incorporated into polymer matrices to create intrinsically colored engineering plastics.

Quality Control

Every batch of our 2,7-Naphthalenedisulfonic Acid derivative is manufactured under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, ensuring traceability and compliance with your internal specifications. Our quality commitment supports applications requiring consistent batch-to-batch performance and reliable supply chain integration.

Storage

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