Description

Disodium 7-[[4-(Ethylphenylamino)-6-Fluoro-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(4-Methoxy-2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate is a high-purity, synthetic organic dye belonging to the class of reactive azo dyes containing a fluorinated triazine group. This compound is engineered for exceptional color fastness and reactivity, making it a critical component in demanding coloration processes. It is primarily required by manufacturers in the textile, leather, and specialty paper industries seeking vibrant and durable hues. Its specific molecular architecture allows for strong covalent bonding with cellulosic and protein-based fibers.

Application

• Reactive Dye for Textiles: Primary application for dyeing and printing cotton, viscose, linen, and other cellulosic fibers, offering excellent wash and light fastness.
• Leather Coloration: Used in the dyeing of leather goods, providing deep, uniform shades with good adhesion.
• Paper Dyeing: Employed in the production of high-grade, colored specialty papers and boards.
• Ink Formulation: A key colorant for certain types of industrial inks requiring specific chromatic properties and stability.
• Research & Development: Serves as a standard or intermediate in chemical research for developing new dye molecules and studying dyeing mechanisms.

Quality Control

Our production of Disodium 7-[[4-(Ethylphenylamino)-6-Fluoro-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(4-Methoxy-2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Every lot is analyzed against comprehensive specifications including purity, shade, and strength. A detailed Certificate of Analysis (COA) documenting identity, assay, impurity profile, and physical parameters is provided with each shipment to support your quality assurance processes.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
