Description

Trisodium [2-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-5-Hydroxy-6-[(2-Hydroxy-5-Sulphophenyl)Azo]Naphthalene-1,7-Disulphonato(5-)]Cuprate(3-) is a high-performance, copper-complexed reactive dye intermediate essential for creating vibrant and wash-fast colors. Its value lies in its ability to form strong covalent bonds with cellulose fibers, resulting in exceptional color yield and superior wet fastness properties. This compound is a critical raw material for manufacturers in the textile, leather, and specialty paper industries seeking to produce high-quality, durable dyes and pigments.

Application

• Reactive Dye Synthesis: Primary intermediate for manufacturing high-grade reactive dyes for cotton, viscose, and other cellulosic fibers.
• Textile Coloration: Used in exhaust, pad-batch, and continuous dyeing processes to achieve deep, complex shades with excellent light and wash fastness.
• Leather Dyeing: Imparts rich, uniform color to leather goods with good penetration and fastness properties.
• Paper and Pulp Coloring: Employed in the production of specialty colored papers requiring high color stability.
• Ink Formulation: A key component in formulating inks for applications demanding specific color characteristics and durability.
• Research & Development: Serves as a standard or building block in chemical R&D for developing new chromophores and dye systems.

Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance. Quality is verified through advanced analytical techniques including HPLC, spectrophotometry, and titration to confirm critical parameters such as purity, color strength, and metal complex content. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 product performance.
