Description

[2-[[4-[(2-Chloro-4-Nitrophenyl)Azo]Phenyl]Ethylamino]Ethyl]Trimethylammonium Hydrogen Sulphate CAS NO 85187-94-6 is a specialized cationic azo dye intermediate, valued for its ability to impart a strong, stable cationic charge to target molecules. This property is crucial for achieving high-affinity bonding to anionic substrates, ensuring excellent color fastness and wash resistance. It is primarily required by manufacturers in the textile, paper, and specialty ink industries for producing high-performance cationic dyes and functional colorants.

Application

• Cationic Dye Synthesis: A key intermediate for manufacturing cationic dyes used in acrylic fiber dyeing.
• Textile Printing: Used in formulations for inks and pastes designed for direct printing on synthetic fabrics.
• Paper Coloring: Employed in the production of cationic dyes for surface coloring and coating of paper products.
• Leather Finishing: Utilized in dye systems for leather to enhance color depth and uniformity.
• Biological Staining: Potential use as a precursor for cationic stains in histology and microscopy applications.
• Functional Polymer Modification: Acts as a monomer or modifier to introduce cationic sites into polymer chains for specialized applications.

Quality Control

Our production of this cationic intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC, UV-Vis, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment 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 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 degradation from atmospheric moisture.
