Description

Trisodium 3-[4-[[5-[[4-fluoro-6-[(o-tolyl)amino]-1,3,5-triazin-2-yl]amino]-2-sulphonatophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]naphthalene-1,5-disulphonate is a high-performance, water-soluble anionic dye belonging to the reactive dye class, characterized by its complex polyazo and triazine-based structure. Its primary value lies in providing exceptional color fastness, brightness, and wash resistance when covalently bonding to cellulosic fibers like cotton and viscose. This compound is essential for industrial manufacturers in the textile dyeing and printing sectors who require durable and vibrant colors for high-quality fabrics.

Application

• Textile Dyeing: Primary application for dyeing cellulosic fibers such as cotton, linen, and viscose, offering excellent wash and light fastness.
• Textile Printing: Used in printing pastes for creating sharp, durable patterns on fabric substrates.
• Leather Coloring: Employed in the dyeing of leather goods to achieve consistent and long-lasting color.
• Paper Coloring: Suitable for specialty paper grades requiring high color intensity and stability.
• Ink Formulation: A key component in the manufacture of certain industrial inks where water solubility and color strength are critical.
• Research & Development: Serves as a standard or intermediate in chemical research for developing new dye molecules and studying chromophore properties.

Quality Control

Our production of Reactive Red 195 adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including color strength, shade, solubility, and impurity profile. Certificates of Analysis (COA) documenting purity, assay, and conformance to specification are available upon request. Our quality system supports compliance with relevant industry standards for textile chemicals.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance and handling properties.
