Description

5-[[4-Chloro-6-(Ethylphenylamino)-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(1-Sulpho-2-Naphthyl)Azo]Naphthalene-2,7-Disulphonic Acid is a high-performance, water-soluble anionic dye belonging to the reactive dye class, valued for its excellent color fastness and strong covalent bonding with cellulosic fibers. Its complex molecular structure, featuring a triazine reactive group and multiple sulphonic acid groups, provides superior wash and light fastness, making it a critical component for demanding coloration processes. This product is essential for manufacturers in the textile, leather, and specialty paper industries seeking vibrant, durable, and consistent shades.

Application

• Textile Dyeing: Primary application for dyeing cotton, viscose, linen, and other cellulosic fibers, offering brilliant shades with high wet fastness.
• Leather Coloring: Used in the dyeing of leather goods, providing deep, uniform color penetration and excellent rub fastness.
• Paper Staining: Employed in the production of high-quality colored papers, security papers, and specialty packaging where color consistency is paramount.
• Ink Formulation: A key pigment component in the manufacture of inks for jet printing and other aqueous-based ink systems.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its specific affinity and color properties.
• Research & Development: Serves as a chemical intermediate or reference standard in synthetic chemistry and dye research laboratories.

Quality Control

Every batch of our Reactive Red 198 is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure it meets precise coloristic and chemical specifications. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as color strength, shade, solubility, and impurity profile. Our quality protocols are designed to support compliance with global standards, including ISO 9001 and relevant ecological and toxicological regulations for dyes.

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 sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials.
