Description

2-Naphthalenesulfonic Acid, 6-Amino-5-5-(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino-2-Sulfo-4-4-2-(Sulfooxy)Ethylsulfonylphenylazophenylazo-4-Hydroxy-, Sodium Salt is a high-purity, reactive dye intermediate belonging to the class of azo dyes containing a triazine ring. This compound matters for its ability to form strong covalent bonds with cellulosic fibers, providing excellent wash and light fastness properties in the final textile product. It is primarily needed by manufacturers in the textile dye and pigment industries for producing high-performance reactive dyes.

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.
• Textile Colorant Production: Used in the manufacture of dyes offering brilliant shades, particularly reds and blues, with superior fastness properties.
• Specialty Pigment Synthesis: Serves as a precursor for certain high-performance organic pigments used in inks and coatings.
• Research & Development: Utilized in chemical R&D for developing new chromophores and studying dye-fiber interaction mechanisms.
• Industrial Dye Manufacturing: Essential for bulk production of dyes destined for the global textile market.

Quality Control

Our 2-Naphthalenesulfonic Acid derivative is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, reactivity, and color strength, meeting the exacting standards required for high-performance dye synthesis. Certificates of Analysis (COA) detailing purity (by HPLC), identity (by IR), and key impurity profiles 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 after each use to prevent moisture absorption and degradation.
