Description

Pentasodium 2-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(2-Sulphonatophenyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Sulphonatobenzoate is a high-purity, water-soluble anionic dye intermediate belonging to the class of reactive dyes and azo compounds. Its value lies in its role as a critical building block for synthesizing high-performance, wash-fast, and light-fast dyes, particularly for demanding textile applications. This compound is essential for manufacturers in the textile, leather, and specialty ink industries seeking to produce vibrant and durable colorants.

Application

• Primary Intermediate for Reactive Dyes: Key precursor in the synthesis of high-quality reactive dyes for cotton, viscose, and other cellulose fibers.
• Textile Dyeing and Printing: Imparts excellent color fastness to washing and light in textile finishing processes.
• Leather Coloring: Used in the production of dyes for achieving deep, uniform, and durable colors on leather goods.
• Specialty Ink Formulation: A component in the manufacture of inks for jet printing and other specialized applications requiring high solubility and color strength.
• Paper Dyeing: Employed in the coloring of high-grade papers where brightness and stability are required.
• Research & Development: Serves as a standard or starting material in chemical R&D for novel dye and pigment synthesis.

Quality Control

Our production of Pentasodium 2-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(2-Sulphonatophenyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]-5-Sulphonatobenzoate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting key parameters are available upon request.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
