Description

bis[bis(2-hydroxyethyl)ammonium] 2'-[4-[[1-[[(2-methoxy-5-methyl-4-sulphonatophenyl)amino]carbonyl]-2-oxopropyl]azo]phenyl]-6-methyl[2,6-dibenzothiazole]-7-sulphonate is a high-purity, water-soluble anionic dye intermediate. This compound is valued for its ability to impart a strong, stable color and its excellent compatibility in aqueous formulations. It is primarily required by manufacturers in the textile, ink, and specialty coatings industries for producing vibrant and durable colorants.

Application

• Textile Dyeing: As a key intermediate for synthesizing reactive and direct dyes for cotton, wool, and nylon fibers.
• Inkjet Inks: Used in the formulation of high-performance color inks for industrial and commercial printing.
• Paper Coloring: Employed in the production of specialty colored papers and coatings.
• Leather Dyeing: Provides consistent and deep coloration for finished leather goods.
• Functional Dye Synthesis: Serves as a precursor for dyes used in optical data storage, LCD color filters, and other advanced materials.
• Biological Staining: Potential use in the development of histological stains for microscopy, given its benzothiazole core structure.

Quality Control

Our bis[bis(2-hydroxyethyl)ammonium] 2'-[4-[[1-[[(2-methoxy-5-methyl-4-sulphonatophenyl)amino]carbonyl]-2-oxopropyl]azo]phenyl]-6-methyl[2,6-dibenzothiazole]-7-sulphonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial dye synthesis. Certificates of Analysis (COA) detailing purity, impurity profile, and physical characteristics 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). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
