Description

2-[6-[4-Fluoro-6-[2-(2-Vinylsulfonylethoxy)Ethylamino]-1,3,5-Triazin-2-Ylamino]-1-Hydroxy-3-Sodiosulfo-2-Naphtylazo]-1,5-Naphthalenedisulfonic Acid Disodium Salt is a high-performance, reactive dye intermediate designed for creating durable colorants. Its molecular structure, featuring a reactive vinyl sulfone group and a triazine ring, enables strong covalent bonding with substrates, resulting in excellent wash and light fastness. This compound is essential for manufacturers in the textile and specialty chemical industries seeking to produce vibrant, long-lasting reactive dyes and pigments.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the synthesis of high-quality reactive dyes for cotton, viscose, and other cellulosic fibers.
• Textile Colorant Production: Used to manufacture dyes that offer superior fixation rates, brilliant shades (particularly reds and blues), and excellent fastness properties.
• Specialty Pigments: Employed in the development of pigments for inks, coatings, and other applications requiring high color strength and stability.
• Research & Development: A valuable compound for R&D laboratories focusing on novel chromophores and advanced dye chemistry.
• Functional Material Synthesis: Potential use in creating colored polymers or materials where covalent attachment of the colorant is required.

Quality Control

Every batch of our reactive dye intermediate is produced under strict quality management and undergoes comprehensive analytical testing to ensure consistent purity and performance. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes specifications for identity, assay, impurity profile, and physical parameters. Our quality systems are designed to meet the rigorous demands of industrial-scale dye manufacturing.

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 product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
