Description

Disodium 2-[4-[[2-Cyano-3-[4-[Methyl(2-Sulphonatoethyl)Amino]Phenyl]-1-Oxoallyl]Amino]Phenyl]-6-Methylbenzothiazole-7-Sulphonate is a high-purity, water-soluble dye intermediate known for its excellent chromophoric properties. This compound is critical for synthesizing advanced reactive dyes that offer superior color fastness and brightness on cellulosic fibers like cotton. It is primarily needed by manufacturers in the textile dyeing and printing industry, as well as by research institutions developing new colorants and functional materials.

Application

• Primary Intermediate for Reactive Dyes: Serves as a key building block in the production of high-performance reactive dyes for cotton, viscose, and other cellulosic fabrics.
• Textile Dyeing and Printing: Used to create vibrant and wash-fast shades in commercial textile dyeing and printing processes.
• Specialty Colorant Synthesis: Employed in research and development for synthesizing novel dyes and pigments with specific optical properties.
• Functional Material Production: Potential applications in the development of light-absorbing materials for sensors or optical filters.
• Laboratory Reagent: Used as a standard or reagent in analytical and quality control laboratories within the color chemistry sector.

Quality Control

Our production of Disodium 2-[4-[[2-Cyano-3-[4-[Methyl(2-Sulfonatoethyl)Amino]Phenyl]-1-Oxoallyl]Amino]Phenyl]-6-Methylbenzothiazole-7-Sulphonate adheres to strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for dye intermediate applications. Certificates of Analysis (COA) documenting purity, impurity profile, and other critical parameters are available upon request to support your quality assurance processes.

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, which can affect product quality and handling properties.
