Description

Tetrasodium 2-[[4-Chloro-6-[[3-[(1-Hydroxy-4-Sulphonato-2-Naphthyl)Azo]-4-Sulphonatophenyl]Amino]-1,3,5-Triazin-2-Yl]Amino]Benzene-1,4-Disulphonate is a high-purity, water-soluble reactive dye intermediate and specialty chemical. This compound is valued for its ability to form strong covalent bonds with substrates, particularly cellulose fibers, resulting in excellent wash and light fastness properties. It is a critical component for manufacturers in the textile, paper, and specialty ink industries seeking to produce vibrant, durable colors. The product's multi-sulfonated structure ensures high solubility and effective application in aqueous systems.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-performance reactive dyes for cotton, viscose, and other cellulosic fibers.
• Textile Printing and Dyeing: Used in formulations for textile printing pastes and dye baths to achieve brilliant shades of red and blue.
• Paper Coloring: Employed in the production of colored paper and paperboard where high color strength and stability are required.
• Leather Dyeing: Applied in the dyeing of leather goods to provide rich, penetrating color with good fastness.
• Inkjet Inks: Serves as a colorant precursor in the formulation of specialty inks for digital textile printing.
• Biological Staining: Potential use as a staining agent in histological and cytological applications due to its chromophoric structure.
• Research & Development: Used in chemical research as a building block for novel chromophores and functional materials.

Quality Control

Our production of Tetrasodium 2-[[4-Chloro-6-[[3-[(1-Hydroxy-4-Sulphonato-2-Naphthyl)Azo]-4-Sulphonatophenyl]Amino]-1,3,5-Triazin-2-Yl]Amino]Benzene-1,4-Disulphonate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and chemical identity. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and solubility are available upon request. Our quality system is designed to meet the specific demands of industrial dye and chemical synthesis.

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 such as strong oxidizing agents.
