Description

Xanthylium, 3-(diethylamino)-9-[2-(ethoxycarbonyl) phenyl]-6-(ethylamino)-, [2,4-dihydro-4-[(2-hydroxy- 5-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol -3-onato(2-)][2-[(4,5-dihydro-3-methyl-5-oxo-1-pheny l-1H-pyrazol-4-yl)azo]benzoato(2-)]chromate(1-) is a complex, high-performance metal-complex dye with a specific chromate anion structure. This compound matters for its ability to provide intense, durable coloration and is engineered for applications requiring high lightfastness and chemical stability. It is primarily needed by manufacturers in the inks, coatings, plastics, and specialty textile industries seeking advanced colorant solutions.

Application

• Industrial Ink Formulation: Used as a key pigment for high-quality printing inks, including packaging and security inks, due to its color strength and stability.
• Automotive and Industrial Coatings: Imparts durable and weather-resistant colors in paint systems for automotive refinish and industrial equipment.
• Plastics and Masterbatch Coloring: Suitable for coloring engineering plastics and polymer resins where thermal stability during processing is required.
• Specialty Textile Dyeing: Employed in dyeing synthetic fibers that require a high degree of colorfastness to light and washing.
• Security and Authentication Features: Potential use in security printing for banknotes, documents, and brand protection due to its complex chemical signature.
• Artist and Specialty Paints: Used in the formulation of high-grade artist paints and pigments where brilliance and permanence are critical.

Quality Control

Our Xanthylium-based pigment is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including color strength, hue, particle size distribution, and chemical purity to ensure consistent performance in your formulations. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing the specifications and test results. Our production adheres to relevant industry standards for colorants and pigments.

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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container must be opaque or stored in darkness to prevent degradation.
