Description

[2-[Ethyl[3-Methyl-4-[(3-Phenyl-1,2,4-Thiadiazol-5-Yl)Azo]Phenyl]Amino]Ethyl]Trimethylammonium Methyl Sulphate is a specialized cationic azo dye intermediate, valued for its ability to impart a permanent positive charge to target molecules. This property is critical for applications requiring strong affinity to negatively charged substrates, such as in the dyeing of synthetic fibers and the preparation of functional materials. It serves as an essential building block for industrial and research chemists in the textile, paper, and specialty chemical synthesis sectors. CAS No. 28313-51-1.

Application

• Cationic Dye Synthesis: Primary intermediate for manufacturing cationic (basic) dyes used on acrylic, modified polyester, and polyamide fibers.
• Textile Dyeing & Printing: Imparts bright, wash-fast colors with excellent substantivity for synthetic fabrics.
• Paper Coloring: Used in the production of dyed papers and paper products requiring high color strength.
• Biological Staining: Potential use as a precursor for cationic stains in histology and microscopy for cell nucleus or tissue staining.
• Ion-Exchange & Chelating Agents: Serves as a functional monomer or modifier in the synthesis of specialty polymers.
• Ink Formulation: A key component in the manufacture of certain types of inks, particularly for non-porous substrates.
• Research & Development: Used in organic synthesis and material science research to create novel charged compounds.

Quality Control

Our production of [2-[Ethyl[3-Methyl-4-[(3-Phenyl-1,2,4-Thiadiazol-5-Yl)Azo]Phenyl]Amino]Ethyl]Trimethylammonium Methyl Sulphate adheres to stringent quality management protocols. Each batch undergoes comprehensive analysis to ensure consistent purity, color strength, and cationic content, meeting the specifications required for high-performance dye intermediates. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and solubility are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product stability.
