Description

Pentasodium 2-[[1-amino-7-[[5-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]-2-sulphonatophenyl]azo]-8-hydroxy-3,6-disulphonato-2-naphthyl]azo]naphthalene-1,5-disulphonate is a high-purity, reactive dye intermediate belonging to the class of chlorotriazine-based azo compounds. This compound is engineered for superior color fastness and covalent bonding to cellulosic and polyamide fibers, making it a critical component in the synthesis of high-performance textile dyes. It is primarily required by manufacturers in the textile, specialty chemical, and ink industries seeking to produce vibrant, wash-resistant colors.

Application

• Primary Intermediate for Reactive Dyes: Key building block for synthesizing high-quality reactive dyes used in cotton, viscose, and other cellulosic fiber dyeing and printing.
• Specialty Ink Formulation: Used in the production of inks for digital textile printing and other applications requiring strong color value and stability.
• Research & Development: Serves as a precise chemical reagent in R&D laboratories for developing new chromophores and functional dyes.
• Leather Coloring: Employed in the formulation of dyes for leather processing, providing deep, even coloration.
• Paper Dyeing: Utilized in the manufacture of dyes for specialty and high-color-fastness paper products.
• Chemical Synthesis: Acts as a versatile intermediate for further chemical modifications to create custom dye molecules and pigments.

Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for critical dye synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing batch-to-batch consistency and reliability for your manufacturing 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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
