Description

2-[[4-[Butyl(2-Cyanoethyl)Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Methyl Sulphate is a specialized cationic azo dye intermediate of significant commercial importance. Its value lies in its ability to impart vibrant, stable coloration to synthetic materials, particularly polyacrylonitrile fibers. This product is essential for manufacturers in the textile and specialty polymer industries seeking to produce high-quality, colorfast synthetic fabrics and materials.

Application

• Primary application as a cationic dye intermediate for the coloration of synthetic fibers, especially acrylic (polyacrylonitrile) and modacrylic fibers.
• Used in the formulation of specialty dyes for the textile industry to achieve bright, wash-fast shades.
• Potential use in the dyeing of other cationic-dyeable substrates, such as certain nylons and polyester blends.
• Employed in research and development for creating novel functional dyes with specific optical or electronic properties.
• May serve as a colorant or intermediate in the production of inks and pigments for specialized applications.
• Applicable in laboratory settings for histological staining or as a biochemical tracer, given its azo chromophore structure.

Quality Control

Our production of this cationic dye intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive analytical testing, including chromatographic purity analysis and strength assessment. A Certificate of Analysis (COA) detailing specific parameters such as assay, hue, and impurity profile is provided with each shipment to guarantee it meets your technical requirements.

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 sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling.
