  • Applications

    Chemical name: 2,2'-(Cyclohexylidenebis((2-methyl-4,1-phenylene)azo))bis(4-cyclohexylphenol); CAS number: 6706-82-7. This bis-azo phenol compound is used primarily as a colorant and dye intermediate in polymers and coatings. It serves as a colorant in printing inks and plastics, offering color development for applications in textiles and packaging where its two phenolic rings contribute to color development and fastness. It also functions as an intermediate in the synthesis of azo dyes and pigments, providing a versatile building block for further dye chemistry. Due to its bis-phenolic structure, it may act as a stabilizer or antioxidant in polymer formulations and coatings, contributing to improved lightfastness and oxidative stability. Additionally, it can be used as an additive in adhesives or as a pigment precursor for specialty coatings, subject to formulation limits and regulatory requirements.
