Description

Barium 4-[(4-Chloro-5-Methyl-2-Sulphonatophenyl)Azo]-3-Hydroxy-2-Naphthoate is a high-purity barium salt of a complex azo dye intermediate, valued for its role in producing vivid and stable pigments. This compound is essential for manufacturers requiring precise colorants with excellent lightfastness and thermal stability for demanding industrial applications. It is primarily sought after by the pigment and specialty chemical industries for creating high-performance red and maroon shades in plastics, coatings, and inks.

Application

• Primary Pigment Intermediate: A key precursor in the synthesis of high-performance organic pigments, particularly for red and maroon colorants.
• Plastics Coloring: Used in the masterbatch and compound production for coloring engineering plastics, PVC, and polyolefins, offering good dispersion and heat resistance.
• Industrial Coatings: Imparts durable coloration to industrial paints, automotive coatings, and powder coatings where weather resistance is critical.
• Printing Inks: Employed in the formulation of specialty printing inks, including packaging and publication inks, for intense color strength.
• Textile Dyes: Serves as an intermediate for developing certain classes of dyes used in textile applications.
• Specialty Chemicals: Acts as a functional intermediate in the research and synthesis of other complex organic molecules.
