Description

2-[[4-[Ethyl[2-(Trimethylammonio)Ethyl]Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Sulphate is a high-purity cationic azo dye intermediate, valued for its intense color properties and structural stability. This compound is essential for synthesizing specialized dyes and pigments with excellent fastness and application performance. It is primarily required by manufacturers in the textile, ink, and specialty chemical industries for producing high-value colorants.

Application

• Textile Dyeing: A key intermediate for cationic dyes used on acrylic, modacrylic, and acid-modified polyester fibers.
• Ink Formulation: Used in the production of high-performance inks for digital, packaging, and security printing applications.
• Biological Staining: Potential application as a specialized stain in histology and microscopy due to its cationic and chromophoric nature.
• Research & Development: Serves as a building block in organic synthesis for novel chromophores and functional materials research.
• Paper Coloring: Employed in the manufacture of specialty colored papers requiring high color strength.
• Liquid Crystal Displays (LCDs): Can be investigated for use in color filters and polarizing films.

Quality Control

Our 2-[[4-[Ethyl[2-(Trimethylammonio)Ethyl]Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Sulphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and identity confirmation via IR and NMR. Certificates of Analysis (COA) documenting all specifications are provided to ensure traceability and compliance with your quality requirements.

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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
