Description

3-Chloro-4-[[4-[[2-(Dimethylamino)Ethyl]Ethylamino]Phenyl]Azo]-N,N,n-Trimethylanilinium Methyl Sulphate is a specialized cationic azo dye intermediate, also known as a basic dye salt. This compound matters for its role as a key precursor in synthesizing high-value, colorfast cationic dyes used in demanding industrial applications. It is primarily needed by manufacturers in the textile, paper, and specialty ink industries who require precise and reliable colorants for synthetic fibers like polyacrylonitrile.

Application

• Cationic Dye Synthesis: A critical intermediate for producing cationic (basic) dyes, particularly for acrylic and modacrylic fibers.
• Textile Dyeing and Printing: Imparts vibrant, wash-fast colors to synthetic fabrics in the textile manufacturing process.
• Paper Coloring: Used in the production of specialty colored papers and paper products requiring high color strength.
• Ink Formulation: Serves as a colorant component in the manufacture of inks for non-porous surfaces and security printing applications.
• Biological Staining: Potential use as a staining agent in histological and microbiological research due to its cationic nature.
• Functional Dye Research: A building block for research into novel dyes for optoelectronics, sensors, and other advanced materials.

Quality Control

Our production of this cationic dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques like HPLC to verify the assay (dye content) and control critical impurities. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical specifications is provided with every shipment to support your quality assurance and regulatory needs.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance and stability.
