Solvent Red 23 CAS 85869 China Suppliers and Factory Manufacturer
Solvent Red 23 is a high-performance synthetic anthraquinone dye specifically engineered for the coloring of non-polar materials. As a professional-grade solvent dye, it is chemically identified as 1-[(4-(Phenylazo)phenyl]azo]-2-naphthol, appearing as a deep red powder. It is highly prized in industrial manufacturing for its exceptional stability and its ability to dissolve seamlessly in organic solvents such as toluene and acetone, while remaining completely insoluble in water.
Designed for rigorous industrial environments, Solvent Red 23 delivers a vibrant, consistent red hue that resists fading under UV exposure and high-temperature processing. Whether utilized as a biological dyeing agent or a marking dye for petrochemicals, this product ensures superior tinting strength and chemical inertness, making it an essential additive for polymers, lubricants, and specialty industrial coatings.
