Description

Tetrasodium [7-(2,5-dihydroxy-KO2-7-sulfonato-6-[4-(2,5,6-trichloro-pyrimidin-4-ylamino)phenylazo]-(N1,N7-N)-1-naphthylazo)-8-hydroxy-KO8-naphthalene-1,3,5-trisulfonato(6-)]cuprate(II) is a high-purity, complex copper phthalocyanine derivative designed for specialized industrial applications. This compound is valued for its exceptional color strength and stability, making it a critical component in advanced material formulations. It is primarily sought by manufacturers in the textile, specialty inks, and high-performance pigment sectors requiring precise and durable coloration.

Application

• Textile Dyeing: Used as a reactive dye for coloring natural and synthetic fibers, particularly cotton, offering excellent wash and light fastness.
• Specialty Inks: A key pigment for high-quality printing inks, including security inks and inks for packaging, where color consistency and durability are paramount.
• Advanced Pigments: Employed in the formulation of high-performance pigments for plastics, coatings, and automotive paints.
• Research & Development: Serves as a sophisticated intermediate or reference standard in chemical research for developing new chromophores and functional dyes.
• Functional Materials: Investigated for use in optoelectronic applications, such as dye-sensitized solar cells (DSSCs) and organic light-emitting diodes (OLEDs), due to its complex structure.
