Description

5-[(5-Chloro-2-Fluoro-6-Methyl-4-Pyrimidinyl)Amino]-4-Hydroxy-3-[(1-Sulpho-2-Naphthyl)Azo]Naphthalene-2,7-Disulphonic Acid, Sodium Salt is a high-purity, water-soluble azo dye intermediate with a complex polycyclic structure. This compound is valued for its ability to impart specific color properties and act as a key building block in the synthesis of advanced colorants. It is primarily required by manufacturers in the specialty dyes and pigments industry, particularly for applications demanding high lightfastness and chemical stability.

Application

• Primary Intermediate for Reactive Dyes: A critical precursor in the synthesis of high-performance reactive dyes used for coloring cotton, wool, and nylon fibers.
• Specialty Pigment Manufacturing: Used in the production of complex organic pigments for inks, coatings, and plastics where specific hue and durability are required.
• Functional Dye Synthesis: Serves as a key component in creating dyes for non-textile applications, such as laser dyes, sensitizers, and biological stains.
• Research & Development: Utilized in chemical R&D for developing novel chromophores and studying structure-property relationships in color chemistry.
• Fine Chemical Production: Acts as a building block for other sophisticated chemical entities in pharmaceutical and agrochemical research.

Quality Control

Our production of this advanced intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and meet precise customer specifications. Certificates of Analysis (COA) detailing purity, impurity profile, and physical characteristics are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture.
