Description

C.I.Cationic Yellow X-5Gl CAS NO 71173-70-1 is a high-purity cationic dye belonging to the methine or polymethine chemical class, valued for its brilliant yellow hue and strong affinity for polyacrylonitrile and other synthetic fibers. This compound is essential for achieving vibrant, wash-fast coloration in textile manufacturing, particularly for materials requiring cationic dye compatibility. It is primarily utilized by industrial dye houses and chemical manufacturers serving the synthetic fiber, paper, and specialty ink sectors.

Application

• Textile Dyeing: Primary application for dyeing acrylic, modacrylic, and acid-modified polyester fibers to achieve bright, lightfast yellow shades.
• Paper Coloration: Used in the production of specialty colored papers, including security papers and decorative stocks.
• Ink Manufacturing: A key colorant for inks used in flexographic, inkjet, and other printing processes on pretreated substrates.
• Leather Finishing: Employed in dyeing leather and synthetic leather products to provide uniform and rich color.
• Biological Staining: Potential use as a cationic stain in microscopy for highlighting cellular structures in histology.
• Plastics and Polymers: For mass coloration of certain plastics where cationic compatibility is required.

Quality Control

Our production of C.I.Cationic Yellow X-5Gl adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and impurity profile. Certificates of Analysis (COA) documenting purity, physical properties, and conformance to specification are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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 and color integrity.
