Description

2,7-Naphthalenedisulfonic acid, 4-amino-6-5-(5-chloro-2,6-difluoro-4-pyrimidinyl)amino-2-sulfophenylazo-5-hydroxy-3-4-2-(sulfooxy)ethylsulfonylphenylazo-, lithium sodium salt is a high-purity, complex anionic dye intermediate and specialty chemical. This compound is engineered for applications requiring precise chromophore properties and excellent water solubility due to its multiple sulfonic acid groups. It is primarily utilized by manufacturers in the textile, ink, and specialty coatings industries for producing vibrant and stable colorants.

Application

• Reactive Dye Synthesis: A key intermediate for manufacturing high-performance reactive dyes for cotton and cellulose fibers.
• Textile Printing Inks: Used in the formulation of inks for digital and screen printing on textiles, offering bright shades and good wash-fastness.
• Functional Dyes: Potential use in the development of dyes for non-textile applications, such as in lasers or as biological stains.
• Specialty Pigments: Serves as a precursor for creating lake pigments and other colorants for industrial coatings and plastics.
• Research & Development: Used in chemical research for synthesizing novel chromophores and studying azo dye chemistry.

Quality Control

Our production of this specialty intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and batch-to-batch reliability. A Certificate of Analysis (COA) detailing specific results for purity, heavy metals, and other relevant parameters is provided with each shipment.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
