Description

2-[[6-[[4-Chloro-6-[(3-Sulphophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-1-Hydroxy-3-Sulpho-2-Naphthyl]Azo]Naphthalene-1-Sulphonic Acid is a high-purity, complex anionic dye intermediate belonging to the reactive dye class. Its core value lies in its ability to form strong covalent bonds with cellulose fibers, resulting in exceptional wash and light fastness properties for the final dyed material. This compound is essential for manufacturers producing premium reactive dyes used in the textile, leather, and paper industries, where consistent color strength and durability are critical.

Application

• Primary intermediate for the synthesis of high-grade reactive dyes and direct dyes.
• Key component in dyes for cotton, viscose, and other cellulose-based textiles, providing brilliant shades.
• Used in the coloration of leather and specialty papers requiring high colorfastness.
• Employed in research and development for creating novel dye molecules with enhanced environmental or performance profiles.
• Potential use as a colorant or intermediate in the production of inks and pigments.

Quality Control

Our production of this dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency in purity and performance. Every lot is analyzed using advanced techniques like HPLC to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with each shipment, supporting your own quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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, which can affect product stability and handling properties.
