Description

[2-[[4-[(2-Cyano-4-Nitrophenyl)Azo]Phenyl]Ethylamino]Ethyl]Trimethylammonium Hydrogen Sulphate is a specialized cationic azo dye intermediate, valued for its ability to impart a strong, stable color and cationic charge to target substrates. Its molecular structure makes it a critical precursor for synthesizing high-performance dyes and pigments used in demanding industrial applications. This compound is essential for manufacturers in the textile, paper, and specialty ink industries seeking to develop products with enhanced color fastness and substrate affinity.

Application

• Textile Dyeing: A key intermediate for cationic dyes used on acrylic fibers, providing excellent wash and light fastness.
• Paper Coloring: Used in the production of cationic direct dyes for paper, offering strong affinity to cellulose fibers for vibrant, bleed-resistant colors.
• Inkjet Inks: Serves as a chromophore in the formulation of specialty inks, particularly for industrial printing requiring high stability.
• Biological Staining: Potential use as an intermediate for cationic stains in histology and microbiology due to its positive charge and chromogenic properties.
• Synthetic Organic Chemistry: Employed as a building block for more complex dye molecules and functional materials research.
• Leather Finishing: Used in the synthesis of dyes for leather, providing deep, penetrating color.

Quality Control

Our production of [2-[[4-[(2-Cyano-4-Nitrophenyl)Azo]Phenyl]Ethylamino]Ethyl]Trimethylammonium Hydrogen Sulphate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee traceability and quality assurance for our global B2B partners.

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 when not in use to prevent absorption of atmospheric moisture, which can affect product performance and handling.
