Description

Dipotassium 3,6-Dichloro-2-(2,4,5,7-Tetrabromo-6-Oxido-3-Oxoxanthen-9-Yl)Benzoate is a high-purity, water-soluble salt derivative of a halogenated xanthene dye, valued for its intense color and stability. This compound is engineered to deliver consistent performance as a critical colorant and functional additive in advanced industrial applications. It is primarily sought by manufacturers in the specialty inks, high-performance plastics, and analytical reagent sectors who require precise chromatic properties and reliable batch-to-batch uniformity.

Application

• Specialty Ink Formulation: A key pigment precursor for high-visibility security inks, flexographic, and gravure printing inks.
• Polymer and Plastic Coloring: Used as a masterbatch additive for coloring engineering plastics and synthetic fibers where lightfastness is required.
• Analytical Chemistry Reagent: Serves as a sensitive colorimetric indicator or staining agent in biochemical assays and diagnostic kits.
• Laser and Optical Materials: Potential application as a dopant in dye lasers or optical filters due to its specific absorption profile.
• Research and Development: Utilized in academic and industrial R&D for synthesizing novel chromophores and functional materials.
• Coatings Industry: Incorporated into specialty coatings where a stable, halogenated dye structure is beneficial for durability.
