Description

Trisodium 7-[[4-chloro-6-[ethyl[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[(4-methoxy-2-sulphonatophenyl)azo]naphthalene-2-sulphonate is a high-purity, water-soluble reactive dye intermediate. This compound is critical for synthesizing high-performance dyes with excellent wash and light fastness properties. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing vibrant and durable colorants.

Application

• Primary Intermediate for Reactive Dyes: Key building block for manufacturing fiber-reactive dyes used in cotton, wool, and nylon dyeing.
• Textile Industry: For the production of dyes offering superior color yield and fixation on cellulosic fibers.
• Ink Formulation: Used in the synthesis of pigments for high-quality inkjet and printing inks.
• Specialty Chemical Synthesis: Serves as a precursor for advanced colorants in research and development.
• Leather Coloring: Intermediate for dyes used in the leather tanning and finishing industry.
• Paper Coloring: For the production of dyes applied in specialty paper manufacturing.

Quality Control

Our trisodium 7-[[4-chloro-6-[ethyl[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[(4-methoxy-2-sulphonatophenyl)azo]naphthalene-2-sulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and performance. Certificates of Analysis (COA) detailing assay, impurity profile, and physical specifications are available upon request to support your quality assurance protocols.

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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
